Utility model content

The problem that utility model will solve

The heat-proof quality that Vacuumed insulation panel is compared existing hard polyurethane foams has for example 6 times of above heat-proof qualities.Therefore,, from the angle grade of energy-saving, in the space being formed between outer container and interior case, except configuration hard polyurethane foams, also configure Vacuumed insulation panel.And along with the raising of the requirement of energy-saving in recent years, the heat insulating box as described in patent documentation 1 for example, the use amount that is disposed at the Vacuumed insulation panel of heat insulating box also increases.

On the other hand, in recent years for heat insulating box, from the angle of the high capacity of save space, internal volume, also require to reduce the space that is formed between outer container and interior case, the i.e. wall thickness of heat insulating box.But existing heat insulating box is that the technological thought based on following is made: hard polyurethane foams is mainly born heat insulating function, the heat insulating function of the auxiliary hard polyurethane foams of Vacuumed insulation panel.At this, existing heat insulating box obtains casing intensity by the space that hard polyurethane foams is filled between interior case and outer container with the density of being scheduled to, but at the thickness that will reduce polyurethane when reducing the thickness of wall, the less thick of polyurethane, the density of polyurethane increases, heat-proof quality declines, and is therefore difficult to meet heat-proof quality and obtains required casing intensity.

; have in the equipment of Vacuumed insulation panel at existing heat insulating box or refrigerator etc.; guarantee the intensity of the heat-proof quality of wall and casing and casing, wall by hard polyurethane foams; reduce the thickness of hard polyurethane foams if reduce the wall thickness of heat insulating box, can produce the heat-proof quality deficiency of heat insulating box or undercapacity and the problem that is difficult to the minimizing that realizes wall thickness.

At this, in the heat insulating box described in patent documentation 1, the use amount (coating rate) of Vacuumed insulation panel increases, the Deflection Modulus of Elasticity (rigidity of hard polyurethane foams) of hard polyurethane foams increases, and therefore from the intensity face of heat insulating box, also thinks and can reduce to a certain extent wall thickness.But, heat insulating box described in patent documentation 1 is mainly to bear heat insulating function and the technological thought of the heat insulating function of the auxiliary hard polyurethane foams of Vacuumed insulation panel is made by hard polyurethane foams, hard polyurethane foams is mainly born heat insulating function, the heat insulating function of the auxiliary hard polyurethane foams of Vacuumed insulation panel, guarantees the heat-proof quality of heat insulating box and the intensity of wall by hard polyurethane foams.But when the less thick of hard polyurethane foams, density, Deflection Modulus of Elasticity can increase, but thermal insulation worsens.Therefore be, that following (Deflection Modulus of Elasticity 10MPa is following, density 60kg/m for predetermined value in order to suppress the decline of heat-proof quality of hard polyurethane foams, set for to make Deflection Modulus of Elasticity, the density of hard polyurethane foams ³below).When Deflection Modulus of Elasticity, density exceed predetermined value, although casing intensity is met, heat-proof quality worsens, thereby is difficult to use.Therefore, heat insulating box described in patent documentation 1 in order to ensure the intensity of casing, wall and heat-proof quality the two, need to guarantee that the thickness of polyurethane is more than to a certain degree, the polyurethane stream thickness that for this reason needs the position that is adjusted to filled polyurethane is the above so that density after polyurethane foam of predetermined thickness following (the density 60kg/m that is predetermined value ³below), thus exist and be difficult to reduce the problem of wall thickness.

In addition, patent documentation 2 conducts possess the intensity measure of the heat insulating box of Vacuumed insulation panel, following Vacuumed insulation panel, interior case, outer container are used: the outsourcing material for Vacuumed insulation panel is shaped to target shape by plastic material etc. by vacuum forming, compressed air moulding etc., fill granular core in inside, thereby be shaped to the concaveconvex shape of having guaranteed intensity.But, to make interior case, outer container be with the convex-concave shape of the concavo-convex basic similar shape of the outsourcing material of Vacuumed insulation panel and embed and make interior case and outer container have intensity, it is complicated that thereby the shape of outsourcing material, interior case, outer container becomes, and has the problems such as cost rising, assembleability deterioration.In addition, from guaranteeing the angle of intensity, Vacuumed insulation panel also needs outsourcing material to be shaped to concaveconvex shape, it is the shape according to the concaveconvex shape of outsourcing material that core in inclosure outsourcing material also needs, therefore core need to use the shot-like particle with mobility, cost raises compared with the fiber-like core such as glass fibre, and heat-proof quality also exists the possibility of variation.In addition, the back side of indoor (accommodation spaces of the reserve in heat insulating box etc.) is concaveconvex shape, complex-shaped, aesthetic appearance variation.

Therefore, in existing heat insulating box or equipment, especially refrigerator, be difficult to guarantee predetermined heat-proof quality and predetermined casing intensity and make the thermal wall or the thermal insulation barriers slimming that comprise Vacuumed insulation panel, therefore, be difficult to the further expansion of the internal volume of realizing heat insulating box, refrigerator, equipment etc. or the miniaturization of appearance and size.

In addition, in the refrigerator described in patent documentation 3, patent documentation 4, by screw, the track component of the box body of the storeroom of support drawer formula or door frame are fixed to thermal wall (the polyurethane thermal insulation barriers between interior case or interior case and outer container or be located at the strengthening part between interior case and outer container).But, when dispose Vacuumed insulation panel between outer container and interior case time, in the case of the thinner thickness of the thermal insulation barriers between Vacuumed insulation panel and interior case, likely because the outsourcing material that the inhomogeneous grade of the thickness of Vacuumed insulation panel causes the hold-down screw damage of track component or door frame or destroy Vacuumed insulation panel causes the decline of the heat-proof quality of Vacuumed insulation panel, the decline of reliability.

In addition, in order not damage Vacuumed insulation panel, can consider the length of the threaded portion of shortening screw, such as, if but the intensity (density, bending resistance elasticity etc.) that is filled in the polyurethane thermal insulation barriers between Vacuumed insulation panel and interior case is less, the maintenance intensity of screw also weak the and thermal wall that is integrally formed with polyurethane intensity also a little less than, therefore likely cause thermal wall or box deformation or screw to fluff, reliability reduces, and therefore flighted length can not be shortened to below predetermined length.Therefore, install by the maintenance such as screw or embedded structure or another fixing parts and (for example support the weight support component of the support such as track component or the door frame weight of box body in the thermal wall with Vacuumed insulation panel, or generate the vibration effect parts of the impact of vibration while being subject to turning round for the cooler of the cold air of cold storage chamber or to the fan of storeroom blowing cooling air etc. etc.) time, the position of installing needs to obtain the wall thickness of installation strength, in addition, according to the relation of the installation strength of screw, the length of the threaded portion of the fixed parts such as screw is for example also difficult to, for below predetermined length (15mm), therefore be difficult to reduce wall thickness, be difficult to increase internal volume.

In Fig. 4, the heat insulating box 700 that forms refrigerator 1 is made up of outer container 710 and interior case 750, between outer container 710 and interior case 750, disposes Vacuumed insulation panel 400.Vacuumed insulation panel 400 is located at the back side of refrigerator 1, directly pastes outer container 710 via PUR, double faced adhesive tape etc. as the 2nd bonding agent of the 2nd sandwiched parts.In addition, Vacuumed insulation panel 400 directly pastes a part (for example, in the forming left and right directions substantial middle portion of the wall at case 750 back sides) for interior case 750 by bonding agent, near left and right end portions (corner part) sidewall 790 except the substantial middle portion at interior case 750 back sides is formed with than back face wall 730 at the outstanding protuberance 450 of front face side, Vacuumed insulation panel 400 is configured to and the overlapping predetermined length of this protuberance 450, but also can exist and not configure Vacuumed insulation panel 400 and the position of filled polyurethane only at protuberance 450.In addition, between interior case 750 and Vacuumed insulation panel 400, be filled with the bonding agent (can use such as hard polyaminoester etc. to have the foaming heat insulation part of self bonding) as the 1st sandwiched parts, Vacuumed insulation panel 400 such as, is located between interior case 750 and outer container 710 via the bonding agent as the 1st sandwiched parts (hard polyaminoester etc.).Therefore, Vacuumed insulation panel 400 is by the 1st sandwiched parts and the 2nd sandwiched adhering components or cementation or be fixed to interior case 750 or outer container 710.

At this, when the back side shape of interior case 750 is seen in the front face side from refrigerator 1 (storeroom side), form the recess 440(of groove shape of upper and lower substantial middle portion depression also referred to as the 1st recess).In the recess 440 forming in this substantial middle portion, Vacuumed insulation panel 400 directly pastes outer container 710 and interior case 750 via bonding agent.In addition,, while seeing from the front face side (storeroom side) of refrigerator 1, the back side shape of interior case 750 becomes width (left and right directions) end side and compares width (left and right directions) substantial middle portion to the outstanding convex form of peristome side (storeroom side) above.In other words, the groove shape that the substantial middle portion that the back side shape of interior case 750 has a left and right directions compares left and right end portions side direction outer container side (rear side of refrigerator) depression is recess 440, and this recess 440 for example, is located at the above-below direction of refrigerator in storeroom (refrigerating chamber 2).

That is, form recess 440 by side 452 and the back face wall 730 of protuberance 450, between the interior case 750 of inner face (storeroom side) of formation back face wall 730 and the outer container 710 of the outside of formation back face wall 730, be provided with tabular Vacuumed insulation panel 400.At this, although not shown, also can between the outer container 710 of the outside of the interior case 750 of the inner face (storeroom side) of formation sidewall 790 and formation sidewall 790, tabular Vacuumed insulation panel 400 be set.Be located at the cold air wind path 760 of back face wall 730 or recess 440, formed by the 2nd wind path accessory 764 that there is the 1st wind path accessory 762 as cap assembly of aesthetic appearance and be located at the rear side (interior case 750 sides) of the 1st wind path accessory 762 and there is thermal insulation, be disposed in recess 440.This 1st wind path accessory 762 as cap assembly or the 2nd wind path accessory 764 have installation portion (holding section), be embedded into and be located at the installation portion (holding section) of protuberance 450 or back face wall 730 or by fixed parts such as screws, installation portion engaged with each other etc., thereby cap assembly 760 is installed to protuberance 450 or back face wall 730.

At protuberance 450 places of left and right end portions side that are formed at the back side in this storeroom, the center side (scope of overlap length X) of width, between outer container 710 and interior case 750, configure Vacuumed insulation panel 400, between Vacuumed insulation panel 400 and interior case 750, be filled with the bonding agent (for foaming heat insulation part 701, for example hard polyaminoester of self bonding) as the 1st sandwiched parts, in addition, between outer container 710 and Vacuumed insulation panel 400 by bonding as the 2nd bonding agent of the 2nd sandwiched parts.The end side of the width of protuberance 450 is such as hard polyaminoester of stuffed heat insulated 701(between outer container 710 and interior case 750), there is the part that Vacuumed insulation panel 400 is not set.Certainly, at protuberance 450 places, increase the configuration area of Vacuumed insulation panel 400 with the Vacuumed insulation panel 400 of increase width at width, can improve heat-proof quality and casing intensity, but cost raises, if therefore heat-proof quality and intensity are more than predetermined value, can set the part that Vacuumed insulation panel 400 is not set.

At this, in recess 440, Vacuumed insulation panel 400 is directly pasted via the 2nd bonding agent as the 2nd sandwiched parts with outer container 710, and Vacuumed insulation panel 400 is pasted with the bonding agent that interior case 750 has self bonding and foaminess via the polyurethane as the 1st sandwiched parts etc.(between Vacuumed insulation panel 400 and interior case 750, be for example filled with the hard polyurethane foams as bonding agent.）

Therefore, in the heat insulating box or refrigerator that possess Vacuumed insulation panel, with such as, as prior art (patent documentation 2), do not arrange compared with polyurethane etc. directly arranges Vacuumed insulation panel 400 at interior case 750 situation taking the heat insulation thermal insulation barriers 701 as main purpose at the configuration section of Vacuumed insulation panel at the width at the storeroom back side, form along the vertical direction in left and right end portions side (width end side) protuberance 450 being formed by the thermal insulation barriers such as polyurethane 701 in the present embodiment, therefore by forming this protuberance 450, can improve the torsional strength of casing, buckling strength.In the formation shown in patent documentation 2, there is not the lap of the configuration section of protuberance 450 and Vacuumed insulation panel 400 at the width at the storeroom back side, therefore in the time that casing reverses, protuberance 450 and Vacuumed insulation panel 400 are cut off, and may produce the worry of intensity decline, casing breakage.At this, the side portion of Vacuumed insulation panel (the only part of outsourcing material) does not have core, does not therefore have heat insulating function, in addition intensity also a little less than, therefore for the side portion of Vacuumed insulation panel, get rid of from the formation accessory of Vacuumed insulation panel.

At this, as shown in the embodiment, at the width at the storeroom back side, protuberance 450 is configured to and the configuration section of Vacuumed insulation panel 400 at least local when overlapping when overlapping with overlap length X (be arranged to), the hard polyurethane foams that is filled into the inside of protuberance 450 is also filled into the part between Vacuumed insulation panel 400 and the interior case 750 of end side of the width (left and right directions) of Vacuumed insulation panel 400, therefore can make to be filled into the thickness of the hard polyurethane foams between Vacuumed insulation panel 400 and the interior case 750 of protuberance 450 position in opposite directions, larger than being filled into thickness with the Vacuumed insulation panel 400 of recess 440 position in opposite directions and the hard polyurethane foams of interior case 750, so, can increase the bond area of hard polyurethane foams with respect to Vacuumed insulation panel 400, and can increase the thickness of the hard polyurethane foams of Vacuumed insulation panel 400 parts, therefore the bond strength of the hard polyurethane foams in protuberance 450 and Vacuumed insulation panel 400 increases.

Therefore, even the thickness of the hard polyurethane foams between Vacuumed insulation panel 400 and the interior case 750 at attenuate recess 440 places, also can significantly improve protuberance 450 and Vacuumed insulation panel 400 and protuberance 450 and sidewall 790(or the surrounding wall of protuberance 450 is set) bond strength, significantly improve the intensity of casing.In addition, at protuberance 450, can increase the thickness of hard polyurethane foams, even if therefore there is the part that Vacuumed insulation panel 400 is not set, heat-proof quality also improves.

In addition, in embodiment of the present utility model, do not need in order to ensure casing intensity, Vacuumed insulation panel, interior case, outer container to be shaped to complicated shape as existing patent documentation 2, in addition, the organic fiber that the core of Vacuumed insulation panel can use at a low price and heat-proof quality is good, the core (cotton shape core, nonwoven core etc.) of inorfil, therefore can obtain low cost, heat insulating box, refrigerator, showcase, the hot water supply device that simple in structure and heat-proof quality is high, possess the equipment etc. of Vacuumed insulation panel.

Therefore, there will not be following situation: for example, box back surface is out of shape and in storeroom, forms concavo-convex; In addition the door of storage room (for example refrigerating-chamber door 7) above that, for example box deformation and making is located at storeroom (for example refrigerating chamber 2) tilts; In addition, the in the situation that of clamshell doors for example, one square neck of the door (7A, 7B) of left and right tiltedly causes dislocation.Therefore, can successfully carry out the switching of door of storage room, in addition, can not cause the dislocation of the door of storage room of left and right, therefore (aesthetic appearance is good) attractive in appearance.In addition, can not cause such as, setting height(from bottom) left and right at the shutter door of the sidewall setting of storeroom (ice-making compartment 3, switch room 4, vegetable compartment 5, refrigerating chamber 6 etc.) inwall or left and right, track component that drawer type box body is used different or tilt because of box deformation, therefore the discrepancy of box body be can successfully carry out, reliability refrigerator high, easy to use, equipment obtained.

In addition, in the time that Vacuumed insulation panel 400 is tabular, Vacuumed insulation panel 400 is being equipped under the state at the back side of refrigerator 1, in left and right directions (width) or easily bending and easily torsion of fore-and-aft direction, about this point, be equipped under the state of the equipment such as refrigerator, if left and right end portions side overleaf forms and is provided with the protuberance 450 of the thermal insulation barriers such as polyurethane and Vacuumed insulation panel 400 and the polyurethane being filled in protuberance 450 are integrally formed at above-below direction, interior case 750, Vacuumed insulation panel 400, outer container 710 is bonding by protuberance 450 one, therefore can improve the buckling strength (buckling strength of direction especially forwards, backwards) of casing 700, torsional strength.Therefore, can suppress front openings storeroom peristome deflection deformation or because dislocation of the seal member of peristome etc. causes the problem of cooling gas leakage, thereby obtain that reliability is high, high-performance and energy-conservation heat insulating box, refrigerator, possess the equipment of Vacuumed insulation panel.

In addition, between interior case 750 and Vacuumed insulation panel 400, there is the position (protuberance 450) arranging taking foaming heat insulation parts such as the heat insulation polyurethane as main purpose, and arrange not taking the heat insulation bonding agent as main purpose (for example, due to not taking heat insulation as main purpose is taking bonding as main purpose, as long as therefore there is self bonding, can be polyurethane etc.) position (recess 440), therefore, arrange taking the position (recess 440) of the bonding bonding agent as main purpose with arrange taking compared with the position of the thermal insulation barriers such as the heat insulation polyurethane as main purpose, without the predetermined thickness of the thermal insulation barriers as for obtaining heat-proof quality, as long as there is predetermined adhesive strength.Therefore for example, can make the thickness of bonding agent quite little taking the bonding position (recess 440) using as main purpose.Therefore, while using hard polyaminoester as bonding agent, compare taking the heat insulation position using as main purpose and can make the thickness of polyurethane quite little.Therefore, the amount that can make wall thickness dwindle the thickness difference of bonding agent, thus can increase the internal volume of storeroom, obtain refrigerator easy to use, equipment.

At this, storage is controlled the driving of distribution, compressor or fan etc. and is managed 720 with the lead-in wire storage member of the lead-in wires such as power line, in above-below direction is embedded in the thermal insulation barriers 701 such as polyurethane of formation protuberance 450.The interior storage of this pipe 720 for carry out various air doors open and close controlling, compressor 12 or circulating cold air fan 14 etc. running control etc. control distribution, for supply with the lead-in wire such as power line of electric power to compressor 12 or circulating cold air fan 14 etc.Control the lead-in wires such as distribution, power line in pipe 720 by and be connected as lower component: be located at the compressor 12 configuring in the Machine Room 1A of bottom (or top) of refrigerator 1; Be located at the back side, bottom surface or the control device above (controlling substrate etc.) 30 of refrigerator 1; Be located at the fan 14 for circulating cold air of cooler chamber 131 grades; Be located at switch room air door 15, the refrigerating chamber air door 55 of cold air wind path; The guidance panel 60 such as, arranging in the shutter door (refrigerating-chamber door 7) such as, arranging in the mode above that covers storeroom (refrigerating chamber 2) etc.

The width of being located at the left and right directions of the Vacuumed insulation panel 400 at the back side of refrigerator 1 is less than the width of 791,792 of the storeroom inner surfaces of the sidewall 790 of refrigerator 1, can not be blocked in multiple filling mouthfuls 703,704 of the thermal insulation barriers such as polyurethane that the end of the left and right directions at the back side of refrigerator 1 arranges, can not stop up the filling stream from filling the thermal insulation barriers such as mouthful polyurethane of 703,704 fillings.

At this, be located at the Vacuumed insulation panel 400 at refrigerator 1 back side left and right directions width when with the storeroom inner surface of the sidewall 790 of refrigerator 1 between the width (distance) of (storeroom is left inside face the wall and meditate 791 and storeroom is right inside faces the wall and meditates between 792) identical or than its hour, can not stop up the filling mouth of the thermal insulation barriers such as polyurethane or fill stream, thereby polyurethane thermal insulation barriers is filled without interruption, can there is not the lower degradation of heat-proof quality, therefore preferred.But as long as Vacuumed insulation panel 400 is configured in and the filling mouth 703 of the thermal insulation barriers such as polyurethane of left and right end portions of rear side of being located at refrigerator 1, 704 allocation position is identical or than filling mouthfuls 703, 704 rely on the position of central side (interior side direction), the filling mouth 703 of polyurethane thermal insulation barriers, 704 just can not blocked by Vacuumed insulation panel 400, therefore can not hinder from filling mouth 703, the thermal insulation barriers such as 704 polyurethane of filling are in sidewall 790, or in protuberance 450, or flow between Vacuumed insulation panel 400 and interior case 750 etc. (being filled), can there is not filling polyurethane bad etc., heat-proof quality also can not decline.

At this, if the inner surface of sidewall 790 that Vacuumed insulation panel 400 is compared refrigerator 1 is outstanding and block at least a portion of the filling mouth 703,704 of polyurethane thermal insulation barriers to width outside, it is mobile that the polyurethane of filling from the filling mouth 703,704 of the thermal insulation barriers such as polyurethane may be intercepted or hinder sidewall 790 in or protuberance 450 in or between Vacuumed insulation panel 400 and interior case 750 etc. by Vacuumed insulation panel 400, may be bad and make heat-proof quality decline in the filling of the thermal insulation barriers such as generation polyurethane such as sidewall.

Therefore, Vacuumed insulation panel 400 is with can not be from being located at the filling mouth 703 of the thermal insulation barriers such as polyurethane of left and right end portions of rear side of refrigerator 1, 704 degree that are exposed to outside are disposed in the scope of the filling mouth 703 in left side (side) of left and right configuration and the inner side of the filling mouth 704 of right side (the opposing party), thereby can not intercept or hinder from filling mouth 703, 704 thermal insulation barriers such as polyurethane of filling are in heat insulating box (between interior case 750 and outer container 710, for example, in sidewall 790, in protuberance 450, between Vacuumed insulation panel 400 and interior case 750, between Vacuumed insulation panel 400 and outer container 710 etc.) filling.Therefore, obtain high performance heat insulating box, the refrigerator that heat-proof quality can not reduce.

At this, Vacuumed insulation panel 400 and interior case 750 via taking the bonding bonding agent as main purpose (can be the foaming heat insulation part with self bonding) directly bonding direct bonding position be recess 440, the stage portion 776 for example for example, with respect to the strengthening part sandwiched position (protuberance 450) that is filled with the strengthening parts such as hard polyaminoester with the projecting height amount of protuberance 450, recess 440 caves in to depth direction (rear side) with respect to protuberance 450.Otherwise, outstanding to the front side of depth direction with respect to the recess 440 as direct bonding position using the amount of stage portion 776 as the protuberance 450 at strengthening part sandwiched position.In addition, Vacuumed insulation panel 400 and interior case 750 via the bonding agents such as the foaming heat insulation part of self bonding directly bonding direct bonding position be recess 440, the step with height (thickness) amount of cold air wind path 760, recess 440 caves in to depth direction (rear side) with respect to the front face side end 769 of cold air wind path 760.Otherwise the end face 769 of the front face side of cold air wind path 760 is outstanding to the front side of depth direction with respect to direct bonding position with the amount of step.

As mentioned above, in the present embodiment, by interior case 750 with outer container 710 forms and possess between interior case 750 and outer container 710 in the equipment such as heat insulating box, refrigerator, cold insulated cabinet, showcase of Vacuumed insulation panel 400, possess: the Vacuumed insulation panel 400 in the back face wall 730 of indoor by being located at (such as, in storeroom) directly pastes the direct bonding position (being recess 440 in figure) of interior case 750 by having the bonding agent such as foaming heat insulation part of self bonding; And between Vacuumed insulation panel 400 and interior case 750 sandwiched for improving the strengthening part sandwiched position (figure is protuberance 450) of the thermal insulation barriers 751 such as the polyurethane as strengthening part of intensity of casing.At this, Vacuumed insulation panel 400 and outer container 710 are directly pasted together by PUR or double faced adhesive tape grade in an imperial examination 2 bonding agents.PUR or double faced adhesive tape grade in an imperial examination 2 bonding agents can apply or stick on Vacuumed insulation panel 400 sides or outer container 710 sides in advance, thickness that therefore can attenuate bonding agent, thereby preferably; But it is uneven or paste unequally to produce coating, therefore between Vacuumed insulation panel 400 and interior case 750, preferably uses the foaming heat insulation part with self bonding.

In addition, in the present embodiment, the width setting of for example strengthening part sandwiched position (for example protuberance 450) and direct bonding position (for example recess 440) sustained height position in storeroom, for example, direct bonding position (for example recess 440) between the strengthening part sandwiched position (protuberance 450) arranging by the left and right end portions of the width in storeroom and the strengthening part sandwiched position of being located at left and right in the mode being clipped by the strengthening part sandwiched position of left and right, and form protuberance 450(strengthening part sandwiched position at the left and right directions at the storeroom back side), between protuberance 450, form the direct bonding position of recess 440().At this, recess 440 and protuberance 450 are from guaranteeing the intensity of casing or guaranteeing the angle of cold air wind path, the preferably roughly whole altitude range setting of the above-below direction in storeroom.

So, with recess 440 position in opposite directions, Vacuumed insulation panel 400 is directly contacted or butt via the 2nd bonding agent with outer container 710, therefore between outer container 710 and Vacuumed insulation panel 400, do not need thermal insulation barriers, can increase storeroom internal volume compared with during with sandwiched thermal insulation barriers.In addition, for example,, at direct bonding position (recess 440), Vacuumed insulation panel 400 is contacted or butt via the foaming bonding agent with cementability with interior case 750.In the present embodiment, for example, at the configuration position of Vacuumed insulation panel 400 (recess 440), there is heat-proof quality and intensity by Vacuumed insulation panel 400, therefore need to be taking the heat insulation thermal insulation barriers as main purpose between interior case 750 and Vacuumed insulation panel 400, with taking heat insulation can attenuate wall thickness compared with during as main purpose sandwiched thermal insulation barriers, therefore can increase storeroom internal volume.At this, while needing mobility as bonding agent, also can use hard polyurethane foams having self bonding etc., thereby it is bonding its foaming to be carried out after interior with two-phase state inflow space 315.

In the present embodiment, can utilize recess 440 as the cold air wind path 760 that the indoor cold air of cold storage is blowed, therefore can make the recess 440 at the storeroom back side that user's hand is difficult to touch be utilized effectively, thereby can use efficiently the storage volume in storeroom.In addition, use have the Vacuumed insulation panel 400 of predetermined intensity (bending strength, buckling strength) and by protuberance 450 in storeroom with the width (preferably can guarantee the degree of torsional strength, buckling strength) be scheduled in the time that above-below direction arranges continuously, can obtain heat insulating box 700, the required intensity of refrigerator 1, and guarantee the buckling strength of torsional strength, fore-and-aft direction or left and right directions therefore can obtain heat insulating box 700, refrigerator 1 that reliability is high.In addition, as long as can obtain the required intensity of heat insulating box 700, refrigerator 1 and guarantee the buckling strength of torsional strength, fore-and-aft direction or left and right directions, protuberance 450, without arranging continuously at above-below direction, also can arrange a place or many places are set intermittently.

In the present embodiment, in storeroom, the left and right end portions side at the back side (width end side) forms the protuberance 450 being made up of thermal insulation barriers 701 such as the polyurethane configuring along the vertical direction, therefore can improve casing 700, the torsional strength of refrigerator 1, buckling strength by forming this protuberance 450.Therefore, the door of storage room (refrigerating-chamber door 7 of for example rotary (radial type)) above that there will not be casing 700 or refrigerator 1 to be out of shape and to make to be located at storeroom (for example refrigerating chamber 2) tilts, for example the in the situation that of clamshell doors, one square neck of the door (7A, 7B) of left and right tiltedly causes the situation of dislocation, therefore can successfully carry out the switching of door of storage room.In addition, can there is not the dislocation of the door of storage room of left and right, therefore attractive in appearance.In addition, the in the situation that of drawer type door, can not make the setting height(from bottom) left and right of the track that the drawer type box body of being located at storeroom (such as ice-making compartment 3, switch room 4, vegetable compartment 5, refrigerating chamber 6 etc.) inwall (sidewall of left and right) 791,792 uses different or tilt because casing 700 is out of shape, therefore can successfully carry out the discrepancy of box body.

At this, in the present embodiment, Vacuumed insulation panel 400, form the intensity that the thermal insulation barriers such as polyurethane of protuberance 450 need to be predetermined, the thermal insulation barriers such as therefore Vacuumed insulation panel 400 uses Deflection Modulus of Elasticity for parts more than 20MPa, the polyurethane of formation protuberance 450 use Deflection Modulus of Elasticity, and for 13.0MPa, (more than being preferably 15MPa), density are greater than 60kg/m above ³(be preferably 62kg/m ³parts above).In the past will by the thermal insulation barriers such as polyurethane obtain casing intensity and heat-proof quality the two, therefore from guaranteeing that the angle of casing intensity need to make polyurethane thermal insulation barriers increase Deflection Modulus of Elasticity, if but increase Deflection Modulus of Elasticity as the characteristic of hard polyaminoester, density increases, and declines if density increases heat-proof quality.Therefore, the in the situation that of polyurethane, in order to obtain predetermined heat-proof quality, it is more than about 10MPa being difficult to make Deflection Modulus of Elasticity, therefore, cannot make the thickness of polyurethane be thinner than for example about 15mm.At this, thinner thickness, the increase storeroom internal volume that more can dwindle wall of the thickness of polyurethane, thereby preferably.But, in order to reduce wall thickness, when the thickness of attenuate polyurethane, the density of polyurethane increases, Deflection Modulus of Elasticity also increases, and therefore can increase casing intensity, but when density increases, heat-proof quality can worsen, and is therefore difficult to make the thickness of polyurethane to be thinner than predetermined value (for example 15mm).

In the utility model, Vacuumed insulation panel 400 uses Deflection Modulus of Elasticity greatly to parts more than 20MPa, therefore disposing the part of Vacuumed insulation panel 400 (casing or wall), can make Vacuumed insulation panel 400 have heat-proof quality and intensity the two, even between outer container and interior case when the thermal insulation barriers such as filled polyurethane, at the position that disposes Vacuumed insulation panel, also without polyurethane is used as setting it as bonding agent taking the heat insulation use of the thermal insulation barriers as main purpose.Therefore, the thermal insulation barriers such as polyurethane can be used as Vacuumed insulation panel 400 and interior case 750 or Vacuumed insulation panel 400 and outer container 710 are carried out to bonding bonding agent, make the heat-proof quality of polyurethane decline even if therefore reduce the thickness of polyurethane also no problem.At this, by making the coating rate (the configuration area of Vacuumed insulation panel 400 is with respect to the ratio of the surface area of casing 700, door) of Vacuumed insulation panel 400 or the filling rate (Vacuumed insulation panel 400 is with respect to the shared V/V in space 315 between outer container 710 and interior case 750) of Vacuumed insulation panel 400 greatly to more than predetermined value, even if there is the position that does not configure Vacuumed insulation panel 400, also can guarantee heat-proof quality, intensity as heat insulating box 700.

Therefore, the position that disposes Vacuumed insulation panel 400 in recess 440 grades between outer container 710 and interior case 750 as shown in the embodiment, by Vacuumed insulation panel 400 have the intensity of casing 700 and heat-proof quality the two time, between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750, can be used as taking the bonding bonding agent as main purpose and use hard polyurethane foams, therefore the thickness of polyurethane can be reduced, the decline of the heat-proof quality of polyurethane can be do not considered.Therefore, even because the thickness of attenuate hard polyurethane foams reduces wall thickness, the heat-proof quality of hard polyaminoester is declined, because the heat-proof quality of casing is born by Vacuumed insulation panel 400, therefore no problem.Thus, can by reduce polyurethane thickness, reduce wall thickness and increase storeroom internal volume.Wherein, can attenuate wall thickness when any one party between outer container 710 and Vacuumed insulation panel 400 or between interior case 750 and Vacuumed insulation panel 400 is used PUR or double faced adhesive tape grade in an imperial examination 2 bonding agent, therefore can increase the volume in storeroom.

At this, the thickness of hard polyurethane foams while use as the bonding agent using between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750 for predetermined value below or while being less than the thickness of Vacuumed insulation panel 400, can reduce wall thickness, therefore can increase the volume in storeroom.At this, when the thickness taking the bonding hard polyurethane foams as main purpose using for any one party between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750 is less than the thickness of Vacuumed insulation panel 400, can obtain the effect that can reduce wall thickness.If the thickness sum of the hard polyurethane foams between the thickness of the hard polyurethane foams between Vacuumed insulation panel 400 and outer container 710 and Vacuumed insulation panel 400 and interior case 750 is less than the thickness of Vacuumed insulation panel 400, can further reduce wall thickness, thereby can increase the volume in storeroom.

In the present embodiment, as the bonding agent using between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750, use hard polyurethane foams, and make the thickness of polyurethane thin as far as possible.But, be not only between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750, Vacuumed insulation panel 400 is not set, only the position of filled polyurethane (in wall) also can use identical hard polyurethane foams.Vacuumed insulation panel 400 is not set and only the position of filled polyurethane (for example part in wall or in protuberance) owing to there not being Vacuumed insulation panel 400, thereby can make the amount of thickness of the thickness increase Vacuumed insulation panel 400 of hard polyaminoester, therefore also can increase the insulating thickness of polyurethane.Therefore, compared with the thickness of the polyurethane filling between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750, can increase the thickness of the polyurethane at the position that does not have Vacuumed insulation panel 400, thereby compared with disposing the density of polyurethane at position of Vacuumed insulation panel 400, can reduce the density of the polyurethane at the position that does not configure Vacuumed insulation panel 400, therefore the heat-proof quality that does not configure the polyurethane at the position of Vacuumed insulation panel 400 improves, and can guarantee predetermined performance.In addition, at the position that does not configure Vacuumed insulation panel 400, can increase the thickness of polyurethane, therefore casing intensity also improves.At this, in the present embodiment, for meet casing intensity and heat-proof quality the two, the filling rate (Vacuumed insulation panel 400 is with respect to the shared V/V in space 315 between outer container 710 and interior case 750) of the coating rate of Vacuumed insulation panel 400 (the configuration area of Vacuumed insulation panel 400 is with respect to the ratio of the surface area of casing 700, door) or Vacuumed insulation panel 400 is greatly to more than predetermined value.

In the present embodiment, there is heat-proof quality, casing intensity by Vacuumed insulation panel 400, therefore can use the thickness of polyurethane thermal insulation barriers to reduce and the intensity that makes polyurethane thermal insulation barriers arrives greatly the parts of 13.0MPa above (preferably more than 15MPa) for Deflection Modulus of Elasticity.In addition, also can use the density of polyurethane thermal insulation barriers to be greater than 60kg/m ³(preferably 62kg/m ³parts above), therefore can reduce the thickness of polyurethane, also can reduce the wall thickness of heat insulating box 700.

(mist device 200)

For example, in the partition wall 51(back face wall 730 of the inboard (rear side) of storeroom (refrigerating chamber 2), as the 1st wind path accessory 762 of wind path cover) or the partition wall at rear of the container back face wall of the roughly closed container that arranges of the bottom of for example, reserve accommodation space 21 in storeroom (refrigerating chamber 2) (for example roughly closed container 2X or 2Y) or the back side partition wall of storeroom (for example vegetable compartment 5) or above partition wall 24, be provided with to the electrostatic atomization apparatus 200 as mist device of supplying with mist in storeroom.

Mist device 200 at least possesses sparking electrode, supplies feedwater or makes sparking electrode generate water and apply voltage to sparking electrode, thereby generate mist at sparking electrode to sparking electrode.To the supply of the water of sparking electrode by cooling heat dissipation portion and producing dew with the hot linked sparking electrode of radiating part.Or in the time that sparking electrode is not thermally coupled with radiating part, the dew generating by cooling heat dissipation portion is supplied to sparking electrode.(can be the structure that sparking electrode doubles as endothermic section, now, radiating part and sparking electrode be thermally coupled, can produce dew at sparking electrode by cooling heat dissipation portion).Or mist device 200 also can at least possess sparking electrode and supply the water supply member of feedwater to sparking electrode, by producing mist from water supply member to sparking electrode for feeding water and applying voltage to sparking electrode.At this, as water supply member, can be to store up the water tank, the heat exchanger (such as cooler 13) etc. that stay water.When water supply member is cooler 13, the container 152 that the defrost water being generated by cooler 13 is configured in cooler chamber 131 is accepted and is retained, and the water in container is supplied to sparking electrode by capillarity etc.At this, while having comparative electrode, the generation of mist is stable, but can not be also comparative electrode, can be gas discharge.

At this, sparking electrode is for example located at, in storeroom (refrigerating chamber 2), in the time being provided with cold air wind path in the partition wall that is being provided with mist device, if radiating part be configured to the partition wall of storeroom (back side or above or below or side) cold air wind path (for example cold air wind path 16 that arranges, 50, 760) wind path wall directly contacts, or via conducting-heat elements mediate contact, or connect wind path wall gives prominence in cold air wind path, by the cold air cooling heat dissipation portion in cold air wind path, producing dew with the hot linked sparking electrode of radiating part, and apply voltage to sparking electrode, thereby generation mist, therefore preferred.

Also can utilize for example, the cold air in another the adjacent storeroom (refrigerating chamber 6) for example, arranging with storeroom (vegetable compartment 5) opposition side with respect to the partition wall of the storeroom that is provided with mist device (above or below or side) to come cooling heat dissipation portion.Now, radiating part is arranged to for example, contact with underside wall or the upper wall of other storerooms (refrigerating chamber) from storeroom side.Mist device 200 can be located at any storeroom as storeroom, can be in refrigerating chamber 2 or vegetable compartment 5 or any storeroom such as chilled chamber 2X, 2Y or container.When mist device 200 is located to back face wall, can be located at the partition wall of a part that is formed in the back face wall arranging between storeroom and cooler chamber.(for example also can be arranged between two adjacent storerooms with temperature difference, on the demarcation strip of (storeroom of high temperature side is that the storeroom of vegetable compartment 5 and adjacent low temperature side is between refrigerating chamber 6), in the storeroom side of high temperature side, mist device is set, one end of radiating part (with the end of sparking electrode opposition side) is arranged to contact with the demarcation strip of other storerooms, utilizes the cold air (utilizing the temperature difference of the storeroom of high temperature side and the storeroom of low temperature side) of the low temperature of the storeroom of low temperature side to come cooling heat dissipation portion.）

As shown in figure 10, Vacuumed insulation panel 400 be located at the back side of refrigerator 1, above, bottom surface.In addition, although diagram not, in side, partition wall 24, door be also provided with Vacuumed insulation panel 400.Be located at the Vacuumed insulation panel 400 at the back side as illustrated in fig. 8, at least in the scope of recess 440, be that the bonding foaming heat insulation part as bonding agent directly pastes outer container 710, interior case 750 by main purpose, use the hard polyurethane foams with cementability as bonding agent, while using hard polyurethane foams, by suitably adjusting free foaming density, in narrow stream (such as, between Vacuumed insulation panel 400 and interior case 750 etc.), also can fill equably.In addition, because the stream narrow also can be bonding, be therefore suitable for hard polyurethane foams as bonding agent, hard polyurethane foams is used as bonding agent.

When main purpose is used hard polyurethane foams as bonding agent, can not consider the reduction of the heat-proof quality causing because of the thickness attenuation of hard polyurethane foams, the thickness that therefore can make hard polyurethane foams is below predetermined thickness, thickness that can attenuate wall (for example back face wall), can increase the volume in storeroom.Can be about 15mm below as the predetermined thickness of bonding agent using hard polyurethane foams when the bonding agent, be preferably below about 11mm, more preferably below about 6mm, in addition, as long as can meet Bao Yuehao more of bonding force (adhesive property) as bonding agent, for example, for the above degree of predetermined thickness (1mm above, be preferably 3mm) is advisable.For example, when thinner than 1mm, the thickness of bonding agent cannot absorb the surperficial roughness (outsourcing material concavo-convex) of Vacuumed insulation panel 400, the surperficial protuberance that produces Vacuumed insulation panel 400 directly contacts with interior case 750 and part that cannot be bonding, may reduce adhesive strength, therefore using hard polyurethane foams when bonding agent uses, likely reduce if cross thin adhesive strength, more than being therefore preferably predetermined thickness.

Certainly, hard polyurethane foams when bonding agent uses, not be can not get to heat-proof quality, although poorer than Vacuumed insulation panel 400, also can obtain the heat-proof quality as thermal insulation barriers.,, when Vacuumed insulation panel 400 is bonded to for example outer container 710 or interior case 750, if use hard polyurethane foams as bonding agent,, except obtaining the effect of heat insulation based on Vacuumed insulation panel 400, can also obtain the effect of heat insulation based on polyurethane.In addition, for the part that Vacuumed insulation panel 400 is not set between interior case 750 and outer container 710, can make the thickness of hard polyurethane foams increase the amount that Vacuumed insulation panel 400 is not set, therefore heat-proof quality is improved.In addition hard polyurethane foams can be used by the bonding agent between interior case 750 and outer container 710.Therefore, the casing intensity of heat insulating box 700 improves, and in addition, heat-proof quality also improves.

(wide bandgap semiconductor)

In control substrate chamber 31, be provided with control device 30, and be provided with the semiconductor such as switch element, diode element accessory, at least a portion semiconductor accessories such as inverting drive circuit use wide bandgap semiconductor.In addition, can in control device 30, only carry semiconductor accessory (can be only wide bandgap semiconductor), also can in carrying semiconductor accessory, carry such as control association accessory (such as, in transformer, relay, converter, power supply reactor, capacitor, current detecting accessory etc. at least one) etc.

In the present embodiment, such as, use wide bandgap semiconductor as the semiconductor accessory (compressor 12, compressor cooling fan, circulating cold air fan 14 etc. drive the inverting drive circuit semiconductor of control use etc.) that is equipped on control device 30.In prior art, be equipped on the semiconductor accessories such as the such as inverting drive circuit accessory of control device 30 and generally use the semiconductor taking silicon (Si) as matrix, but use in the present embodiment wide bandgap semiconductor, as wide bandgap semiconductor, use such as carborundum (SiC), gallium nitride (GaN), diamond, aluminium gallium nitride alloy (AlGaN) etc.

Wide bandgap semiconductor (such as carborundum SiC, gallium nitride, gallium nitride (GaN) etc.) comprises following 2 points with respect to the semi-conductive advantage of silicon (Si).First advantage be the loss of element little, can high temperature action.The caloric value of Si many and at approximately 100 DEG C～200 DEG C semiconducting behavior reduce, dyskinesia, therefore need to arrange the fin (radiator) of heat transmission and further via air heat radiation, need to be used for carrying the storage volume of fin and the space for dispelling the heat.With respect to this, the switching losses for example, in the situation of wide bandgap semiconductor (SiC) in element is less, energy-conservation,, until 300 DEG C of left and right are all difficult to occur the reduction of performance, therefore can in the hot environments such as Machine Room 1A, use simultaneously.In addition, due to until 300 DEG C of left and right are all difficult to occur the reduction of performance, therefore have advantages of and do not need the fin of heat transmission or can make the fin of heat transmission very little (height and size diminishes, thinning, miniaturization).

Second advantage is to dwindle the thickness that forms the device of accessory as semiconductor.The insulation breakdown electric-field intensity of wide bandgap semiconductor (for example SiC, GaN) is larger, therefore semi-conductive withstand voltage large (have approximately 10 times of silicon (Si) withstand voltage), therefore can make the thickness of semiconductor devices little (thin) to 1/10 left and right.In the present embodiment, there is the wide bandgap semiconductor of this specific character by use, can realize inverting drive circuit accessory significantly miniaturization, thinning, needn't worry structure of heat dissipation environment etc., therefore can obtain the second best in quality refrigerator under the large and small type of the free degree and the hot environment of design.

The semiconductor accessory such as inverting drive circuit accessory that is equipped on control device 30 uses wide bandgap semiconductor, and therefore insulation breakdown electric-field intensity is large, withstand voltage large, thereby can reducing thickness and size (being about 1/10 compared with silicon).In addition, under the high temperature of 300 DEG C, also can move, therefore can make the radiating fin (radiator) of the cooling use of semiconductor accessory minimum.Therefore, be semiconductor accessory for having at the state that is equipped on control device 30 the inverting drive circuit accessory of comparing the high radiator of other control association accessory equal altitudes in prior art, can extremely reduce in the present embodiment the height that radiator and inverting drive circuit accessory are coordinated by using wide bandgap semiconductor, size is (vertical, horizontal width) (thinning, miniaturization), therefore can under the state that is equipped on control device 30, will highly be reduced to and other control association accessories (for example power supply reactor, capacitor, transformer, current detecting accessory etc.) the equal degree of height, or the height below equal extent.

At this, also Vacuumed insulation panel 400 is directly pasted to outer container 710 or controlled substrate chamber 31 by bonding agent disposing the part of controlling substrate chamber 31, for example, be filled to suitable hard polyurethane foams being set in as bonding agent to predetermined thickness (the above preferably 3mm of 1mm above and below the following preferred 6mm of 11mm) between Vacuumed insulation panel 400 and interior case 750.

In addition, in the present embodiment, be configured to by control substrate chamber 31 be located at refrigerator 1 above and with Vacuumed insulation panel 400 will be heat insulation around, and the semiconductor accessory such as inverting drive circuit accessory is while using wide bandgap semiconductor, even if control that surrounding's Vacuumed insulation panel 400 of substrate chamber 31 or polyurethane thermal insulation barriers cover, to make to control substrate chamber 31 interior also no problem under hot environment.In addition, when the semiconductor accessories such as inverting drive circuit accessory use wide bandgap semiconductor, also can be configured in the Machine Room 1A under hot environment controlling substrate chamber 31.Even if wide bandgap semiconductor also can be difficult for breaking down moving compared with existing Si semiconductor under hot environment, therefore use thermal insulation barriers Coverage Control substrate chamber 31 also no problem.In addition, also without being set around controlling substrate chamber 31, thermal insulation barriers etc. carries out heat insulationly becoming high temperature with the temperature that prevents from controlling in substrate chamber 31 while being configured in the Machine Room 1A under hot environment by controlling substrate chamber 31, therefore the design of controlling substrate chamber can be simplified, compressor, equipment cheaply can be obtained.In addition, due to without to control substrate chamber 31 heat insulation, therefore can make to control the corresponding height of the big or small attenuate of substrate chamber 31 and the amount of thickness of thermal insulation barriers (or reducing width, depth) and miniaturization, therefore during by the direct bonding Vacuumed insulation panel 400 of bonding agent and control substrate chamber 31, Vacuumed insulation panel 400 and interior case 750, without the polyurethane of filling as thermal insulation barriers, the wall thickness that therefore can reduce to arrange the wall (such as upper wall, back face wall etc.) of controlling substrate chamber 31, can correspondingly increase storeroom internal volume (case internal volume).

In addition, control the surrounding space (the such as upper space of the terminal box of compressor 12, lateral space (or surrounding space) etc.) that substrate chamber 31 can arrange the compressor 12 that the relation because of space cannot arrange in the prior art, therefore the free degree (free degree of design) of controlling the setting of substrate chamber 31 improves, and can obtain the equipment such as refrigerator, air conditioner that can effectively utilize such as Machine Room 1ANei space.

(defrosting heater, defrost water utilization)

Dispose compressor 12 at the Machine Room 1A that is located at the back side foot of refrigerator 1 (or back side topmost).Refrigerator 1 has freeze cycle, and compressor 12, for forming an accessory of freeze cycle, is disposed at Machine Room 1A, has the effect of the cold-producing medium in compression freeze cycle.The cold-producing medium being compressed by compressor 12 is condensed in condenser (not shown).The cold-producing medium of the state being condensed is depressurized in the capillary as decompressor (not shown), expansion valve (not shown).Cooler 13, for an accessory of the freeze cycle of formation refrigerator, is disposed at cooler chamber 131.The cold-producing medium being reduced pressure by decompressor evaporates in cooler 13, the heat-absorbing action during by this evaporation, and the gas of cooler 13 peripheries is cooled.Circulating cold air is disposed near of cooler 13 in cooler chamber 131 with fan 14, for the cold air being cooled at cooler 13 peripheries such as, is blown into the each chamber as storeroom (refrigerating chamber 2, ice-making compartment 3, switch room 4, vegetable compartment 5, refrigerating chamber 6) of refrigerator 1 via cold air wind path (switch room cold air wind path 16, refrigerating chamber cold air wind path 50 etc.).

Be located at cooler 13 in cooler chamber 131 below be provided with the Glass tube heater of the defrosting heater 150(defrosting of the conduct defrosting member of the defrosting of carrying out cooler 13, be for example to have used in quartz glass tube, to send through the carbon heater of the carbon fiber of the light of the wavelength 0.2 μ m～4 μ m of quartz glass tube etc.).Between cooler 13 and defrosting heater 150, be provided with heater top cover 151 on the top of defrosting heater 150, directly fall defrosting heater 150 with the defrost water that prevents from falling from cooler 13.If defrosting heater 150 uses the heater of the black media such as carbon heater, can effectively melt by radiant heat transfer the frost of cooler 13, therefore can make surface temperature is low temperature (approximately 70 DEG C～80 DEG C), for example, in the time that cold-producing medium for freeze cycle uses combustible refrigerant (as the iso-butane of hydrocarbon refrigerant etc.), also can reduce the danger of catching fire even if there is refrigrant leakage etc.In addition, can effectively melt by radiant heat transfer the frost of cooler 13 compared with nichrome wire heater, therefore tie in the frost of cooler 13 and melt gradually, frost is difficult to into piece and plunks, therefore can reduce the sound that falls while falling heater top cover 151, the refrigerator that low noise and defrosting efficiency are good can be provided.

At this, defrosting heater 150 can be the heater that one is assembled into the embedded type of cooler 13.In addition, also can be used together glass tubular type heater and embedded type heater.The defrost water being generated by cooler 13 or fall the defrost water of heater top cover 151, falls and is discharged to refrigerator outside (being for example located at the evaporating pan of Machine Room 1A etc.) via the defrosting water holding department 154 of being located at below cooler chamber 131 from defrost water outlet 155 cooler is indoor.

At this, in the time being provided with these two coolers (evaporimeter) of refrigerating chamber cooler and refrigerating chamber cooler, with in cooler, compared with cooler, can evaporating temperature be set highlyer with refrigerating chamber at refrigerating chamber, thereby it be less to be attached to the frost of cooler.Therefore, do not need defrosting heater 150, thereby do not need heater top cover 151 yet.Therefore the defrost water, being generated by cooler 13 is directly fallen the defrosting water holding department 154 of the bottom of being located at cooler chamber 131 and is discharged to refrigerator outside (being for example located at the evaporating pan of Machine Room 1A etc.) from defrost water outlet 155 cooler is indoor.

In the time being provided with these two coolers (evaporimeter) of refrigerating chamber cooler and refrigerating chamber cooler, the storeroom back side at rear or the back side of vegetable compartment 5 in the bottom of refrigerating chamber 2 (roughly closed container 2X, 2Y) arrange refrigerating chamber cooler, therefore mist device 200 are located to back face wall or roughly the storeroom back face wall at the rear at the back side of closed container 2X, 2Y or the back face wall of vegetable compartment 5 etc. of the reserve accommodation space of refrigerating chamber 2.As the water supply member of mist device 200 can use by refrigerating chamber cooler generate defrost water, and substitute in cooler chamber 131, be disposed at cooler 13 below heater top cover 151 and configuration accept by refrigerating chamber cooler generate defrost water and retain container.Now, in the time that water overflows from being located at the water outlet container on top of container, the water overflowing if make is discharged to refrigerator outside from defrost water outlet 155, does not need to process the water overflowing from being located at the water outlet on container top.Therefore, container can be located in cooler chamber 131, container is located at refrigerating chamber and is used the below of cooler and the top of defrost water outlet 155.In addition, if the sparking electrode of mist device 200 be located at container top position and and position (the front face side position of cooler) or refrigerating chamber cooler and the container of refrigerating chamber cooler equal height between position, in the time that being supplied to sparking electrode by capillarity etc., can shorten in the water in container the feed path of water, and therefore preferred.

Mist device 200 can be configured to as shown in the figure its at least a portion and be accommodated in the recess of upper wall (above partition wall 24) of the vegetable compartment 5 of adjacent setting below refrigerating chamber 6, utilize and the cold air arranging in other storerooms (refrigerating chamber 6) of the adjacent setting in top of storeroom (vegetable compartment 5) of mist device 200, make radiating part produce dew, and use this dew to apply voltage to sparking electrode, make sparking electrode produce mist.

At Fig. 9, Tu10Zhong, storeroom interior lighting device 900 is for example located at the roof (upper wall) 740 as the inwall of the refrigerating chamber 2 of storeroom, is made up of multiple LED.At this, also lighting device 900 can be located to sidewall 790, underside wall 780, the partition wall 24 in storeroom.The leading edge that multiple LED of lighting device 900 compare shelf 80 is located at the front face side of refrigerator 1, can not can be covered and irradiates equably in storeroom from top to below by shelf 80.In addition, at least one in multiple LED of lighting device 900 for example, for example, configures optical axis in the mode that can irradiate the door storage portion that is located at door of storage room (refrigerating-chamber door 7) in the time opening door of storage room (refrigerating-chamber door 7), therefore when dim around the refrigerators such as night 1, not only can irradiate in storeroom, can also irradiate a storage portion, therefore can obtain user's refrigerator easy to use.

The example more than for example, being formed by another accessory (the 1st wind path accessory 762) with respect to the interior case 750 that forms recess 440 for the cold air wind path 760 of being located at storeroom back face wall, but also can make the 1st wind path accessory 762 one-body molded or form by interior case 750.Now, by being shaped at the interior case of substantial middle portion position of width (left and right directions) that forms the recess 440 that the interior case 750 of back face wall forms at the protuberance of above-below direction Formation cross-section circular-arc (or arched door shape or U word shape) and this protuberance to side-prominent in storeroom, substitute the 1st wind path accessory 762.And, can use as cold air wind path 760 in the space between protuberance and the Vacuumed insulation panel 400 of the circular shape (or arched door shape or U word shape) being become by this interior box-shaped.When only the protuberance by this circular shape and Vacuumed insulation panel 400 are difficult to form cold air wind path 760, the 2nd wind path accessory 764 of the spatial placement cross section elliptical shape between protuberance and Vacuumed insulation panel 400 etc.While substituting the 1st wind path accessory 762 by interior case 750 like this, do not need the 1st wind path accessory 762, without the 1st wind path accessory is assembled into interior case 750 etc., can improve assembleability, therefore can obtain that accessory number is few, low cost and good heat insulating box, refrigerator, the equipment of aesthetic appearance.

In Figure 22, the rear side configuration of heat insulating box 700, for filling or inject the filling mouth (inlet) 703,704 of hard polyurethane foams etc., near four jiaos of the back face wall part except the Machine Room 1A of the lower backside of being located at heat insulating box 700 or upper rear portion, (near four bights) are provided with 4 places.Fill mouthfuls 703,704 allocation position be located at left end or the right-hand member from casing 700 on width leave preset distance Y1, on above-below direction from upper end or the end of lower end or Machine Room 1A leave the position of preset distance Y2.At this, if when the width length (being diameter in the situation of circle) that the thickness of sidewall 790 is T1mm, filling mouth is r1, for the packing materials such as polyurethane when from packing materials such as filling mouthful (inlet) 703,704 filled polyurethanes can flow swimmingly in sidewall 790, the preset distance Y1 of width is preferably below T1+r1.The for example thickness of sidewall 790 is about 20mm～50mm, fill mouthfuls 703,704 diameter r1 while being about 25mm～50mm, fill mouth 703,704 if make and leave such as 10mm of preset distance T01mm(from the end of sidewall 790) to configure, preset distance Y1 becomes below the above T1+r1 of T01+r1, is therefore preferably below the above 80mm of about 35mm.

In addition, during from packing materials such as filling mouthful (inlet) 703,704 filled polyurethanes, if roof or underside wall or to the thickness of the heat insulation partition wall of separating between Machine Room and storeroom be T2mm, establish the above-below direction length of filling mouthful (circle situation under for diameter) during for r2, for the packing materials such as polyurethane can be flowed in roof or in underside wall or in partition wall swimmingly, the preset distance Y2 of above-below direction is preferably below T2+r2.Because the thickness of roof or underside wall or partition wall is that about 20mm～50mm, the diameter r2 that fills mouth 703,704 are about 25mm～50mm, fill mouth 703,704 if therefore make and leave such as 10mm of preset distance T02mm(from the end of wall) to configure, preset distance Y2 becomes below the above T2+r2 of T02+r2, is therefore preferably below the above 80mm of about 35m.

At this, while being provided with as shown in Figure 8 to indoor (storeroom in) side-prominent protuberance 450, if filling mouth 703,704 can be filled swimmingly in the scope (scope of the predetermined position 797,798 that the hypotenuse 456 of the general triangular of protuberance 450 is connected with back face wall 730 or sidewall 790) that is provided with protuberance 450, therefore in the time that the width length of establishing protuberance 450 is A, preset distance Y1 is preferably below the above T1+A of T01+r1, and in the time that the above-below direction length of establishing protuberance 450 is B, preset distance Y2 is preferably below the above T2+B of T02+r2.Therefore, the length A of protuberance 450 is during for 180mm～200mm for example, preset distance Y1 is until be 250mm following (being preferably about 230mm following), even if the packing materials such as the polyurethane being filled are encountered the hypotenuse portion (can be also circular-arc) 456 of protuberance 450, because hypotenuse portion tilts, therefore also can be injected into swimmingly sidewall 790, roof 740 etc., therefore no problem.

(forming track component at sidewall)

At this, the situation of orbit portion (for example track or track installation portion) 755 of the storeroom (door or the drawer box body etc. of such as drawer type) that is formed for supporting shelf 80 or drawer type at sidewall 790 is described.

Figure 24 is near the major part cutaway view of track installation portion of the refrigerator of embodiment of the present utility model.Figure 25 is near the major part cutaway view of track installation portion of another refrigerator of embodiment of the present utility model.Figure 26 is near the major part cutaway view of track installation portion of another refrigerator of embodiment of the present utility model.Figure 27 is near the major part cutaway view of track installation portion of another refrigerator of embodiment of the present utility model.In Figure 24～Figure 27, to being marked with same-sign with the equal part of Fig. 1～Figure 14 and description thereof is omitted.In addition, in Figure 24～Figure 27, equal part is marked with same-sign, is therefore omitted in the explanation in other figure a figure explanation.

In Figure 24, on sidewall 790, at for example refrigerating chamber 2, vegetable compartment 5, in refrigerating chamber 6 storerooms such as grade, the orbit portion (such as track component installation portion or track maintaining part) 755 that stays at the shelf 80 of storeroom or the storeroom of drawer type (door or the drawer box body etc. of such as drawer type) for propping up is formed by interior case recess 717 or the interior case protuberance of convex form etc. of concave shape in interior case 750, the thermal insulation barriers 701 such as interior case 750 or strengthening part 731 or polyurethane are fixed in the rail supported portion 820 of track component 810 by track fixed parts 735 such as screws.Therefore, at sidewall 790, if below the thickness that is filled in the thermal insulation barriers 701 such as the hard polyurethane foams as the 3rd sandwiched parts between Vacuumed insulation panel 400 and interior case 750 is set as predetermined thickness (below about 11mm, be preferably less than 10mm, more preferably below about 6mm) with attenuate wall thickness, increase storeroom internal volume, for fixing or keep the fixed part such as screw of track component or strengthening part may damage or destroy the outsourcing material of Vacuumed insulation panel 400.

At this, while shortening the length of the fixed parts 735 such as screw in order not damage Vacuumed insulation panel 400, for constant intensity or the maintenance weakened of fixing or maintenance track component 810, in the time that track component 810 is provided with box body 520, shelf 80 etc. and storage or is placed with reserve, may cause fixed part 735 to depart from from interior case 750 because of the weight of reserve, box body 520, shelf 80 etc.In addition, situation at the drawer type box body of 2 grades of track structures is inferior, pull-out quantitative change in pull-out when box body 520 is large and in the time that track component 810 is provided with box body 520 etc., may because of the weight of reserve, box body 520 etc. cause orbit portion 755 with the mounting portion distortion of the interior case 750 of track component 810 or strengthening part 731 position in opposite directions, appearance cannot pull out the situation of drawer type box body 520 swimmingly.At this, the length (length of threaded portion) of inserting and be fixed on the fixed parts 735 such as the screw in polyurethane 701 is if will guarantee intensity, be difficult to be shorter than about 10mm, conventionally more than will guaranteeing about 15mm, thereby the thickness that is difficult to the hard polyurethane foams 701 that makes conduct the 3rd sandwiched parts between Vacuumed insulation panel 400 and interior case 750 is about 15mm following (preferably 11mm following (it is good being for example less than 10mm)).Especially, the polyurethane using in prior art is in order to ensure heat-proof quality, little of 60kg/m in density ³following scope is used, and therefore polyurethane internal pore is more, keeps the intensity of the fixed parts such as screw less, therefore needs to make the length of the fixed parts such as screw longer.

In embodiment of the present utility model, on the sidewall 790 of heat insulating box 700 or refrigerator 1, an orbit portion (for example track installation portion or track maintaining part) 755 that is used for staying at the shelf 80 of indoor (storeroom etc.) or the box body of drawer type (door or the drawer box body etc. of the storeroom of such as drawer type or storeroom) 520 is formed to interior case 750, and and the interior case 750 at the orbit portion 755 of this interior case 750 position in opposite directions and outer container 710 between dispose Vacuumed insulation panel 400.At this, and the interior case 750 at the orbit portion 755 of interior case 750 position in opposite directions and outer container 710 between while configuring Vacuumed insulation panel 400, by the fixed parts such as screw 735 be not be located at sidewall 790 but be located at form partition wall 24 below of chamber or form chamber above partition wall (upper wall) 24 or roof 740 or underside wall 780 be advisable.Now, fixed part is located near underside wall 780 or partition wall 24 below or partition wall 24 or the roof 740 above of of sidewall 790, therefore underside wall 780 or below partition wall 24 or roof 740 or above partition wall 24 while also configuring Vacuumed insulation panel, position or the excision etc. of avoiding arranging fixed part 735 configure Vacuumed insulation panel 400.Thus, can configure Vacuumed insulation panel 400 at sidewall 790, and can attenuate wall thickness.

In addition, in embodiment of the present utility model, even if the length (length of threaded portion) at the fixed part 735 such as screw of the polyurethane 701 interior insertions that use as the 3rd sandwiched parts is less than about 10mm, when the density of the polyurethane as the 3rd sandwiched parts is greater than 60kg/m ³scope use time, space and density in polyurethane are less than 60kg/m ³in time, is compared and tails off, and keeps the intensity of the polyurethane of the fixed parts 735 such as screw to increase, and therefore the maintenance intensity of fixed part 735 improves.Now, can between Vacuumed insulation panel 400 and interior case 750, form resin or metal tabular strengthening part (screw fixed part) 731 and fixed part 735 is inserted to screw fixed part 731 etc. and be fixed.The thickness of strengthening part 731, as long as keeping or the thickness of the fixed part 735 such as hold-down screw, is set as below the above 10mm of about 2mm.Now, if be greater than 60kg/m as the density of the polyurethane of the 3rd sandwiched parts ³also can increase the maintenance intensity of strengthening part (screw fixed part) 731 in polyurethane 701, therefore orbit portion 755, the distortion of fixed part 735 etc. of interior case 750 can be suppressed, the dislocation of strengthening part 731 in polyurethane 701 etc. can be suppressed in addition.Especially in the case of 2 grades of track structures with 2 grades of pull-outs, need to make the fixing of fixed part or keep intensity larger, if but the density of polyurethane is greater than 60kg/m ³, just can use without problems.In addition, be that 11mm following (being for example less than 10mm) and the flighted length that is preferably the fixed parts 735 such as 6mm is following, screw are below 10mm even if establish the thickness of the thermal insulation barriers such as polyurethane 701, due to threaded portion to the outstanding contraction in length of polyurethane thermal insulation barriers 701 thickness (for example 1～2mm) amount of interior case 750 or thickness (for example about 1mm～8mm) amount of strengthening part 731 of the part of hold-down screw 735 (orbit portion 755), therefore can there is not screw 735 yet and damage or destroy the situation of Vacuumed insulation panel 400.

; between interior case 750 and outer container 710, Vacuumed insulation panel 400 is set; arranging on the sidewall 790 of the track component 810 that drawer type storeroom uses; with the thickness of the foaming heat insulation part (for example hard polyurethane foams) 701 at the orbit portion (track installation portion) 755 of attachment rail parts 810 position be in opposite directions below 11mm; thickness/(thickness of the thickness+Vacuumed insulation panel of foaming heat insulation part) of foaming heat insulation part is below 0.3, and the density of hard polyurethane foams is greater than 60kg/m ³, thereby the disengaging of the fixed parts such as screw 735 be can suppress or maintenance intensity or the constant intensity of the fixed part 735 such as screw increased, orbit portion 755 can not be out of shape, and therefore can successfully carry out the discrepancy of box body 520 grades.In addition, the orbit portion of the fixed parts such as mounting screw 735 (track installation portion) 755 or interior case 750 can be not damaged, and reliability improves.

Track component 810 is by forming using lower component: fixing or be held in the shutter door 7,8,9,10,11 of storeroom 2,3,4,5,6 and be drawn out along with opening of shutter door get on the right track 811 as moving track; Be fixed on the lower railway 812 as trapped orbit of the sidewall 790 of storeroom; Be located at get on the right track 811 and lower railway 812 between intermediate orbit 813; Be fixed to the rail supported portion 820 of lower railway 812 by the rail supported such as screw or welding portion fixed part 836; Be fixed to by the box body such as screw or welding support portion fixed part 835 811 the box body support portion 830 of getting on the right track; For support intermediate orbit 813 with get on the right track 811 and lower railway 812 between the multiple bearings 815 as rotary supporting part that engage.Rail supported portion 820 is fixed to the orbit portion 755 of the interior case 750 of the sidewall 790 that forms storeroom 2,3,4,5,6 by track fixed parts 735 such as screws.In addition, 830 of box body support portions stay at the box body 520 of storeroom 2,3,4,5,6, follow the movement as 811 the fore-and-aft direction of getting on the right track of moving track, box body 520 moves and (follows 811 the movement of getting on the right track along fore-and-aft direction, box body 520 moves along fore-and-aft direction, thereby box body 520 is come in and gone out along fore-and-aft direction).In addition, intermediate orbit 813 is followed and is got on the right track 811 movements at fore-and-aft direction and move along fore-and-aft direction.Therefore, the box body 520 of each storeroom 2,3,4,5,6 with each door of storage room 7,8,9,10,11 is synchronously moved forward and backward together with 811 with getting on the right track along fore-and-aft direction pull-out with respect to refrigerator 1, when each door of storage room standard-sized sheet, box body 520 is understood dismounting upward freely.

At this, lower railway 812 and rail supported portion 820 can be formed., can lower railway 812 and rail supported portion 820 be waited fixing integratedly in advance by welding.Now, do not need the screw as rail supported portion fixed part 836, assembleability is improved.In addition, also a part for lower railway 812 can be used as rail supported portion 820, now, not need welding, screw etc., therefore can obtain track component, refrigerator that low cost and assembleability are good.

The orbit portion 755 of the interior case 750 of the sidewall 790 that forms each storeroom is fixed or is held in by the rail supported portion 820 of track component 810 by track fixed part 735.At this, track component 810 has size to a certain degree, therefore under the state of storeroom side that is installed on orbit portion 755, can stretch out (giving prominence to) to storeroom side, thereby, in order to dwindle to the overhang (overhang) in storeroom, preferably orbit portion 755 is observed to outer container 710 directions depressions from storeroom side.Thus, the orbit portion 755 of interior case 750 becomes to the shape of outer container 710 direction depressions, case recess 717 in forming.By making like this orbit portion 755 to the interior case recess 717 of outer container 710 sides depressions from storeroom side attachment rail parts 810, can increase volume in storeroom and the volume of box body 520.

In outer container 710 sides (with the opposition side of storeroom side) of the orbit portion 755 of interior case 750, and Vacuumed insulation panel 400 between be provided with strengthening part 731, between strengthening part 731 and Vacuumed insulation panel 400, be filled with the thermal insulation barriers such as polyurethane 701 as the 3rd sandwiched parts, strengthening part 731 is fixed in the mode of being substantially close to by the thermal insulation barriers such as polyurethane 701 or is held in orbit portion 755.Between the orbit portion 755 and outer container 710 of interior case 750, be provided with successively thermal insulation barriers 701, Vacuumed insulation panel 400, the outer containers 710 such as orbit portion 755, strengthening part 731, polyurethane from interior case 750 sides.At this, in the present embodiment, the thermal insulation barriers 701 such as filled polyurethane between interior case 750 and Vacuumed insulation panel 400, heat-proof quality and casing intensity are provided by Vacuumed insulation panel 400, therefore also can substitute thermal insulation barriers 701 and use bonding agent as the 3rd sandwiched parts, now can be used as the hard polyurethane foams of the foaming heat insulation part with self bonding as bonding agent.In addition, outer container 710 and Vacuumed insulation panel 400 are fixed as the 2nd bonding agent of the 2nd sandwiched parts by PUR or double faced adhesive tape etc.

At this, more than the thickness Q of the thermal insulation barriers 701 such as the polyurethane of filling between Vacuumed insulation panel 400 and interior case 750 is set to about 15mm (more than being preferably 13mm).In addition, the thickness P of the thermal insulation barriers 701 such as the polyurethane of filling between Vacuumed insulation panel 400 and the orbit portion 755 of interior case 750 is set to below 11mm and (is for example less than 10mm), therefore can increase the Deflection Modulus of Elasticity of the thermal insulation barriers such as polyurethane 701, improve the intensity of casing 700 or refrigerator 1.In addition, the thickness R of the thermal insulation barriers 701 such as polyurethane of filling between strengthening part 731 and Vacuumed insulation panel 400 is set to be less than predetermined thickness P, for example, for below about 6mm, therefore can further improve intensity.In addition, the density of the thermal insulation barriers 701 such as polyurethane is configured to be greater than 60kg/m ³, therefore can improve maintenance intensity or the constant intensity of the fixed parts such as screw 735, suppress becoming flexible, depart from or coming off of screw.In addition, can improve maintenance intensity or the constant intensity of strengthening part 731, the distortion of the distortion of the screw that suppress the generation of the dislocation of strengthening part 731, causes because misplacing, the orbit portion 755 of interior case 750, can obtain refrigerator, equipment that reliability is high.

In Figure 25, strengthening part 731 is metal system or resin, by the tabular strengthening part body 734 for fixed part 735 is fixed, extension 732 on the tabular strengthening part of being located at the upper end of strengthening part body 734 or top and stretch out along general horizontal direction, under the tabular strengthening part of being located at the lower end of strengthening part body 734 or bottom and stretch out along general horizontal direction, extension 733 forms, strengthening part body 734, extension 732 on strengthening part, under strengthening part, extension 733 is formed one (being assembled into one) or one-body molded.

Strengthening part 731 bonds to outer container 710 rear flank of the interior case recess 717 forming at the orbit portion 755 of interior case 750 by double faced adhesive tape or PUR grade in an imperial examination 2 bonding agents, fixed or be held in the orbit portion 755 of interior case 750 by the thermal insulation barriers such as filled polyurethane 701.Strengthening part 731 is formed as the cross section U-shaped that on strengthening part, under extension 732 and strengthening part, extension 733 stretches out to equidirectional from the end face of strengthening part body 734, and be located at extension 732 in the bottom surface sections (depressed part), strengthening part of interior case recess 717 with strengthening part body 734 and be configured to the position relationship in opposite directions with the recess epimere portion 718 that forms interior case recess 717, strengthening part 731 is located to outer container 710 sides of interior case recess 717.In addition, under strengthening part extension 733 be configured to the recess hypomere portion 719 that forms interior case recess 717 in opposite directions.Thus, strengthening part 731 can make on strengthening part extension 733 under extension 732 or strengthening part easily position with respect to interior case 750.In addition, strengthening part 731 can be mounted to from outer container 710 sides and cover interior case recess 717, therefore be easy to carry out location or the installation of strengthening part 731 inside casees 750, in addition, the intensity of interior case recess 717 is also improved.At this, strengthening part 731 is as long as form any one party of extension 733 under extension on strengthening part 732 or strengthening part or moulding, just can position with recess epimere portion 718 or recess hypomere portion 719 by extension under extension on strengthening part 732 or strengthening part 733, therefore can omit any one party (as long as any one party is set).

In addition,, in Figure 25, rail supported portion 820 is integrally formed by welding with the lower railway 812 as trapped orbit of track component 810, is therefore easy to the assembling of the orbit portion 755 that carries out track component 810 inside casees 750.In addition, track component 810 loads the recess hypomere portion 719 as track component mounting portion in interior case recess 717 via rail supported portion 820 or as the lower railway 812 of trapped orbit, track component 810 is positioned in mode that can not be mobile downwards, in addition, be provided with fixing by screw etc. or keep the fixed part of rail supported portion 820 at the upper face side of recess hypomere portion 719, to suppress rail supported portion 820 or track component 810 upward or fixed part (mobile suppressing portion) is fixed or be held in to the mode of horizontal movement.

Track component 810 is loaded in the recess hypomere portion 719 as track component mounting portion, therefore suppress the problem of being out of shape because of the weight of box body 520 for the rail supported portion 820 of supporting track parts 810 downwards, thereby can carry out swimmingly the discrepancy of door or box body 520.At this, box body 520 is made up of box bottom wall, four box side walls, is the container of opening above, on manufacturing, is provided with pattern draft, and the box side wall that forms box body 520 from top downward, tilt to the central axis direction of box body 520., to be formed as lower end narrower than upper end for the width of box body 520.

Therefore, the gap (length) between box body 520 and sidewall 790 is that the lower end of box body 520 is larger than upper end.Thus, in the time that box body 520 is supported by track component 810, track component 810 can increase the volume of box body 520 while support below the short transverse of box body 520, therefore preferred.By for example box body support portion 830 of track component 810() the height of box body 520 below 1/2, preferably box body 520 is supported in the position below 1/3 time can increase the width of box body, therefore can increase the volume of box body 520.Now, can box body stage portion 525 be set at the box side wall of box body 520, support box body stage portion 525 by the box body support portion 830 of track component 810.Can easily support thus box body 520.In addition, can be near the lower end of the short transverse of box body 520 (for example height of box body 520 below 1/2 preferably the position below 1/3) support, if but the back side of the box bottom wall as is bottom supported, just, without box body stage portion 525 being set at box body 520, be easy to carry out the manufacture of box body 520.

To form track mounting portion be interior case 750 and Vacuumed insulation panel 400(or the outer container 710 of recess hypomere portion 719) between the such as hard polyurethane foams of thermal insulation barriers 701(such as the polyurethane of filling) density be greater than 60kg/m ³time, track component mounting portion is that the intensity of recess hypomere portion 719 is improved, even if therefore receive weight at box body 520, the track component mounting portion of mounting track component 810 is that recess hypomere portion 719 also can not be out of shape, thereby can stably carry out the discrepancy of box body 520, can obtain refrigerator, equipment that reliability is high.

In addition, at Figure 24, Tu25Zhong, interior case recess 717 can be received at least a portion (such as rail supported portion 820 etc.) of track component 810 or all, therefore can reduce the overhang of track component 810 to storeroom side, therefore, the volume in storeroom can be increased, in addition, the volume of box body 520 can also be increased.

At Figure 24, Tu25Zhong, the example that strengthening part 731 is set for outer container 710 sides of the interior case recess 717 forming from storeroom side observation depression at interior case 750 is illustrated, and Figure 26 is the example that strengthening part 731 is set from outer container 710 sides of the outstanding interior case protuberance 727 forming of storeroom side observation at interior case 750.In figure, the interior case 750 that forms sidewall 790 makes orbit portion 755 side-prominent to storeroom, and is formed with interior case protuberance 727.Interior case protuberance 727 has protuberance epimere portion 728, protuberance hypomere portion 729, forms convex form by protuberance epimere portion 728, protuberance hypomere portion 729.

In Figure 26, interior case protuberance 727 observes from outer container 710 sides the recess shapes that is depression, in the recess of outer container 710 sides that is formed at this interior case protuberance 727, be accommodated with strengthening part 731(storage at least a portion or whole), carry out the above-below direction of strengthening part 731 or horizontal location by protuberance hypomere portion.In addition, by receive at least a portion of strengthening part 731 or all in the recess of outer container 710 sides that is formed at interior case protuberance 727, can reduce the overhang of strengthening part 731 to outer container 710 sides, therefore when at Vacuumed insulation panel 400(or outer container 710) and interior case 750 between when the thermal insulation barriers 701 such as filled polyurethane, width (thickness of the thermal insulation barriers 701 such as polyurethane between Vacuumed insulation panel 400 and the strengthening part 731) R that can suppress the stream that polyurethane flows through narrows and causes polyurethane to be difficult to mobile situation.Therefore, flowing of the thermal insulation barriers such as polyurethane 701 can not be obstructed, thereby between strengthening part 731 and Vacuumed insulation panel 400, can fully guarantee the thickness R of the thermal insulation barriers such as polyurethane 701, thereby can suppress the reduction of the fixing or maintenance intensity of the track such as reduction or the screw fixed part 735 of the maintenance intensity of strengthening part 731.

In addition, rail supported portion 820 is that lower railway 812 is waited and is integrally formed by welding with the trapped orbit of track component 810, is therefore easy to the assembling of the orbit portion 755 that carries out track component 810 inside casees 750.In addition, rail supported portion 820 is positioned in partition wall 24 or the bottom surface sections 780 be located between storeroom, and track component 810 is positioned to can not move downwards, in addition, be provided with fixing by screw etc. or keep the fixed part of rail supported portion 820 in partition wall 24 or bottom surface sections 780, and to suppress rail supported portion 820 or track component 810 upward or fixed part (mobile suppressing portion) is fixed or be held in to the mode of horizontal movement.At this, be provided with Vacuumed insulation panel 400 at partition wall 24 or bottom surface sections 780.

Track component 810 is located at outer container 710 sides of the interior case recess 717 of interior case 750 in Figure 24, Figure 25, in Figure 26, be located at outer container 710 sides of interior case protuberance 727, but track component 810, without being located at interior case recess 717 or interior case protuberance 727, also can be located at the par of interior case 750 as shown in figure 27.

In Figure 27, track component 810 is located at the orbit portion 755 of interior case 750, and orbit portion 755 is fixed on the tabular surface of interior case 750 by the fixed parts such as screw 735.In addition, be provided with strengthening part 731 at the face of outer container 710 sides of orbit portion 755, strengthening part 731 by and Vacuumed insulation panel 400 between the thermal insulation barriers 701 such as the polyurethane of filling be fixed or keep.Now, strengthening part 731 is bonding or be fixed under the state of interior case 750 and be filled thermal insulation barriers 701 by PUR or double faced adhesive tape grade in an imperial examination 2 bonding agents, thereby is kept or is fixed on the face of outer container 710 sides of interior case 750.

In Figure 27, same with Figure 24～Figure 26, the density of the thermal insulation barriers such as polyurethane 701 is greater than 60kg/m ³, therefore maintenance intensity or the constant intensity of the fixed part 735 such as screw are improved, and have suppressed becoming flexible, depart from or coming off of screw.In addition, maintenance intensity or the constant intensity of strengthening part 731 are improved, and the distortion of the distortion of the screw that can suppress the generation of the dislocation of strengthening part 731, causes because misplacing, the orbit portion 755 of interior case 750, can obtain refrigerator, equipment that reliability is high.

In addition, the thickness P of the thermal insulation barriers 701 such as polyurethane of filling between Vacuumed insulation panel 400 and the orbit portion 755 of interior case 750 is set to below 11mm and (is for example less than 10mm), is preferably below 6mm, therefore can increase the Deflection Modulus of Elasticity of the thermal insulation barriers such as polyurethane 701, improve the intensity of casing 700 or refrigerator 1.In addition, that the thickness R of the thermal insulation barriers 701 such as polyurethane of filling between strengthening part 731 and Vacuumed insulation panel 400 is configured to is less than predetermined thickness P, for example, for below about 6mm, thereby can further improve intensity.

In addition,, in Figure 27, the end of the orbit portion 755 of interior case 750 (for example lower end) is formed with interior case 750 to the side-prominent protuberance 757 of storeroom, is placed with the rail supported portion 820 of track component 810 on this protuberance 757.This protuberance 757 is configured to less to the outstanding length of width than track component 810 to the outstanding length of the width of storeroom side, can not compare track component 810 to outstanding in storeroom, thereby the volume that can suppress storeroom volume, box body volume diminishes.

In addition, rail supported portion 820 is that lower railway 812 is waited and is integrally formed by welding with the trapped orbit of track component 810, is therefore easy to track component 810 to be assembled into the orbit portion 755 of interior case 750.In addition, rail supported portion 820 is loaded the upper face side of the protuberance 757 forming in the end at orbit portion 755 (lower end), and track component 810 is positioned to can not move downwards, in addition, be provided with fixing by screw etc. or keep the fixed part of rail supported portion 820 at the upper face side of protuberance 757, and to suppress rail supported portion 820 or track component 810 upward or fixed part (mobile suppressing portion) is fixed or be held in to the mode of horizontal movement.

At this, at Figure 24, in Figure 26, orbit portion 755 is located near of partition wall 24 or underside wall 780, therefore track component 810 is installed near of partition wall 24 or underside wall 780, box body 520 is supported at the lower position of short transverse, therefore the mounting intensity of track component 810 is improved, thereby preferably, and at Figure 25, in Figure 27, orbit portion 755 has preset distance G with partition wall 24 or underside wall 780, therefore track component 810 can be installed on top with preset distance G with respect to partition wall 24 or underside wall 780, thereby can make the Support Position of box body 520 in top, can carry out swimmingly the discrepancy of box body.In addition,, owing to can shortening the length of box body support portion 830 of track component 810, therefore intensity is improved, and obtains track component, refrigerator cheaply.

At this, can box body stage portion 525 be set, support box body stage portion 525 by the box body support portion 830 of track component 810 at the box side wall of box body 520.Thus, can easily support box body 520.In addition, can be below the short transverse of box body 520 or near lower end (for example height of box body 520 below 1/2 preferably the position below 1/3) support, if but the back side of the box bottom wall as is bottom supported, just, without stage portion 525 being set at box body 520, be easy to carry out the manufacture of box body 520.

At interior case 750 and Vacuumed insulation panel 400(or the outer container 710 of side-prominent orbit portion end (orbit portion protuberance) 757 to storeroom forming as track mounting portion) between the such as hard polyurethane foams of thermal insulation barriers 701(such as the polyurethane of filling) density be greater than 60kg/m ³time, intensity as the orbit portion end 757 of track component mounting portion is improved, even if therefore receive weight at box body 520, the track component mounting portion of mounting track component 810 is that orbit portion protuberance 757 also can not be out of shape, therefore the discrepancy of box body 520 can be stably carried out, refrigerator, equipment that reliability is high can be obtained.

At this, track component 810 can be located at sidewall 790, also can be located at the partition wall (being included in the partition wall arranging between storeroom and storeroom and the bottom surface that forms storeroom or partition wall 24 or underside wall 780 or roof 740 above) of the storeroom of configuration track component 810., the rail supported portion 820 of supporting track parts 810 can be located to (or load in) partition wall (comprising partition wall 24 or roof 740 or underside wall 780).If like this rail supported portion 820 of supporting track parts 810 is located to the partition wall 24 of storeroom, just without at sidewall 790, fixed part 735 being set, therefore can increase the thickness at the Vacuumed insulation panel 400 of sidewall configuration, in addition can dwindle, the thickness of the thermal insulation barriers 701 such as the polyurethane of filling between Vacuumed insulation panel 400 in sidewall 790 and interior case 750.Therefore, can increase volume in storeroom or the volume of box body 520.

At this, in the situation that rail supported portion 820 is located to partition wall, in partition wall 24 or underside wall 780 or roof 740, be not advisable at the position configuration Vacuumed insulation panel 400 that track fixed part 735 is set.In addition,, if be provided for the strengthening part of the fixed parts such as hold-down screw in the position that track fixed part 735 is set, the constant intensity of fixed part or maintenance intensity are improved.In addition, when filling or apply or configure the thermal insulation barriers such as hard polyurethane foams or foam styrene between Vacuumed insulation panel 400 and the profile parts of formation partition wall, if make the density of thermal insulation barriers be greater than 60kg/m ³, fix or keep the fixed part of track component 810 or the maintenance of strengthening part or constant intensity to be improved, therefore reliability improves.

Above to using the orbit portion of interior case 750 755 from storeroom, the fixing situation such as screw for inner side (situation between orbit portion 755 and the Vacuumed insulation panel 400 of interior case 750 is located in the threaded portion of being located at storeroom 2,3,4,5,6 sides, fixed part 735 as the head of screw of the screw of fixed part 735) is illustrated.But also can make the screw 735 of fixed part give prominence to and fix to storeroom 2,3,4,5,6 is interior from the private side of sidewall 790, now, head of screw is located between the orbit portion 755 of Vacuumed insulation panel 400 and interior case 750 (thermal insulation barriers 701 such as orbit portion 755 or track strengthening part 731 or polyurethane is fixed in threaded portion), even but in this case, because the density of polyurethane is greater than 60kg/m ³therefore the constant intensity of the thermal insulation barriers 701 such as the thermal insulation barriers such as the fixed part such as strength increase, screw 735 and polyurethane 701, interior case 750 and the polyurethane of polyurethane 701 or keep strength increase, thereby the dislocation of the distortion of interior case etc., strengthening part 731, screw is loosening etc. suppressed, can make box body 520 grades pull out swimmingly (can come in and go out swimmingly).

In embodiment of the present utility model, by and interior case 750 and the Vacuumed insulation panel 400 of position in opposite directions, the position that track component is set of sidewall 790 between the thickness of foaming heat insulation part (for example hard polyurethane foams) be set as 11mm following (being preferably less than 10mm), thereby can increase the Deflection Modulus of Elasticity of polyurethane, therefore can be in maintaining the intensity of wall attenuate wall thickness.In addition, by and interior case 750 and the Vacuumed insulation panel 400 of position in opposite directions, the position that track component is set of sidewall 790 between the thickness of foaming heat insulation part (for example hard polyurethane foams) be set as 6mm when following, can further increase the Deflection Modulus of Elasticity of polyurethane, therefore can be in maintaining the intensity of wall attenuate wall thickness.

In addition, by the thickness of foaming heat insulation part/(thickness of the thickness+Vacuumed insulation panel of foaming heat insulation part) is set as below 0.3, attenuate wall thickness can dwindle the composite guide heating rate of the composite component that foaming heat insulation part and Vacuumed insulation panel are combined, even if therefore also can improve heat-proof quality.

In addition, by making the density after polyurethane foam be greater than 60kg/m ³, can be in maintaining the intensity of wall attenuate wall thickness.

As above, in embodiment of the present utility model, and interior case 750 and the Vacuumed insulation panel 400 of position in opposite directions, the position that track component is set of sidewall 790 between the thickness of foaming heat insulation part (for example hard polyurethane foams) be (to be preferably less than 10mm) below 11mm, the thickness of foaming heat insulation part/(thickness of the thickness+Vacuumed insulation panel of foaming heat insulation part) is set as below 0.3, and makes the density after polyurethane foam be greater than 60kg/m ³time, further attenuate wall thickness in maintaining the intensity of wall.At this, the thickness that the thickness of the foaming heat insulation part in above formula is polyurethane, therefore, as the thickness of foaming heat insulation part, can be the thickness R at thermal insulation barriers 701 such as the thickness P of the thermal insulation barriers 701 such as the polyurethane of filling between Vacuumed insulation panel 400 and the orbit portion 755 of interior case 750 or the polyurethane between thickness Q or Vacuumed insulation panel 400 and the strengthening part 731 of the thermal insulation barriers 701 such as the polyurethane of filling between Vacuumed insulation panel 400 and interior case 750.For example, when the thickness that makes foaming heat insulation part is the thickness R of the thermal insulation barriers 701 such as the polyurethane between Vacuumed insulation panel 400 and strengthening part 731, by the thickness of the thickness R+ Vacuumed insulation panel of the thickness R/(foaming heat insulation part of foaming heat insulation part) be set as below 0.3.Equally, while making thickness be P or Q, thickness R is replaced as to P or Q.In addition, the thickness of the polyurethane shown in Figure 17, Figure 18, Figure 19 can be equally also the thickness R at thermal insulation barriers 701 such as the thickness P of the thermal insulation barriers 701 such as polyurethane of filling between Vacuumed insulation panel 400 and the orbit portion 755 of interior case 750, polyurethane between thickness Q, Vacuumed insulation panel 400 and the strengthening part 731 of the thermal insulation barriers 701 such as the polyurethane of filling between Vacuumed insulation panel 400 and interior case 750.

In addition, be more than 20MPa if make the Deflection Modulus of Elasticity of Vacuumed insulation panel 400, further attenuate wall thickness.At this, can not that track component is fixed to sidewall 790, but be fixed near the underside wall 780 of sidewall 790 or partition wall 24 or upper wall (roof) 740 or the partition wall 24 above of bottom surface.At this, and interior case 750 in opposite directions of position that the fixed parts such as screw are set and outer container 710 between while not configuring Vacuumed insulation panel 400, the underside wall 780 of fixed part or partition wall 24 below or roof 740 or partition wall above 24 are set and are preferably the wall or the partition wall that do not contact with outer gas.Such as, reduce at the wall contacting with outer gas (sidewall 790, roof 740, back face wall 730, underside wall 780 etc.) position that Vacuumed insulation panel 400 is not set as far as possible, the loss causing because of heat leak be can reduce, high performance heat insulating box, refrigerator, equipment therefore can be obtained.Thus, can increase the configuration area of the Vacuumed insulation panel 400 of back face wall 730, sidewall 790, therefore can increase coating rate or the filling rate of the Vacuumed insulation panel 400 in heat insulating box 700.

At this, the heat insulating box 700 of present embodiment 1, mainly to bear this prior art thought of heat insulating function different from the hard polyurethane foams in heat insulating box 700, and it is based on make Vacuumed insulation panel 400 bear heat-proof quality and this new technological thought of casing intensity in the part that disposes Vacuumed insulation panel 400.The filling rate (volume of Vacuumed insulation panel 400 is with respect to the shared ratio of cumulative volume in space 315 in the wall forming between outer container 710 and interior case 750) of the Vacuumed insulation panel 400 in the wall that therefore, the heat insulating box 700 of present embodiment 1 makes to form between outer container 710 and interior case 750 in space 315 is more than predetermined value (being for example more than 40% (to be preferably more than 45%)).At this, the filling rate of Vacuumed insulation panel 400 also comprises that the volume of Vacuumed insulation panel 400 is the filling rate of door with respect to the shared ratio of volume in space in the door between external door panel and the door inner panel of the profile of formation door.

In prior art, so that the mode of the Vacuumed insulation panel area ratio (coating rate) shared with respect to the surface area of outer container 710 or interior case 750 in predetermined scope configures Vacuumed insulation panel, and do not consider the impact of the thickness of Vacuumed insulation panel 400, therefore make the thickness of Thickness Ratio Vacuumed insulation panel 400 of hard polyurethane foams large, to there is the intensity of heat insulating box by hard polyaminoester.The coating rate that will increase Vacuumed insulation panel 400 in prior art improves the heat-proof quality of casing, but the filling rate that does not increase Vacuumed insulation panel 400 improves heat-proof quality and casing intensity both sides, therefore the filling rate of Vacuumed insulation panel 400 less (for example the filling rate in existing refrigerator is approximately 20%), the situation that exists heat-proof quality not improve, and casing intensity-dependent is in hard polyurethane foams.In the present embodiment, configure Vacuumed insulation panel 400 in the mode of filling rate of the thickness of having considered Vacuumed insulation panel 400, therefore can not improve as prior art heat-proof quality.Be predetermined value above (for example, more than 40%) by making the filling rate of Vacuumed insulation panel 400, heat-proof quality is improved, and can be in meeting casing intensity, heat-proof quality attenuate wall thickness, therefore can increase storeroom internal volume, more than desired product storeroom internal volume can being set as to predetermined capacity.That is, can suitably set length, width, thickness, the configuration position of Vacuumed insulation panel 400, can reduce wall thickness, can correspondingly increase storeroom internal volume.

By increasing compared to existing technology like this filling rate of the Vacuumed insulation panel 400 in space 315, heat-proof quality is increased compared to existing technology, even if the therefore wall thickness of attenuate heat insulating box 700 compared to existing technology, also can guarantee that heat-proof quality is more than the equal extent of prior art.

(other of the 1st wind path accessory form)

As mentioned above, in embodiment of the present utility model, such as the width of the width Length Ratio recess 440 of the 1st wind path accessory 762 of a part for the formation cold air wind path 760 shown in Fig. 4, Fig. 5, Fig. 6, Fig. 8 etc. is little, is fixed or is kept by the fixed parts such as screw or hooking structure or embedded structure etc. at protuberance 450 or the 2nd recess 441 or the jut 910 etc. that forms the 2nd recess 441.At this, the width length of the 1st wind path accessory 762 that can make a part that forms cold air wind path 760 is to cover the mode of a part of back face wall 730 or sidewall 790 and reach the inner face of sidewall 790 and the 1st wind path accessory 762 is fixing or remain to the inner face of sidewall 790 by the fixed parts such as screw or hooking structure or embedded structure etc.Certainly, the inner face of sidewall 790 not only can be fixed or remain to the 1st wind path accessory 762, can also fix or remain to jut 910, recess 440, protuberance 450 etc. by fixed part or hooking structure or embedded structure etc.

In addition, thereby the width length that forms the 1st wind path accessory 762 of a part for cold air wind path 760 if make reaches the inner face of sidewall 790 and not only covers the 2nd recess 441 and also cover at least a portion of recess 440, protuberance 450 or all, the 1st wind path accessory 762 can be also used as the Appearance Panel, can the back face wall of covering chamber's (for example storeroom) or at least a portion of the inner face of sidewall or all, can be using the 1st wind path accessory 762 as the cap assembly use of a part that covers the back side or side.Therefore, when being located at the 1st wind path accessory 762 to indoor supply from the supply port of the cold air of cold air wind path 760, can improve the free degree of configuration, collecting article in cooling chamber efficiently, in addition, the 1st wind path accessory 762 can use another parts different from interior case 750, therefore can easily change shape or color or carry out all processing, coating or literature record etc., and functional, aesthetic appearance is improved.The 1st wind path accessory is also used as to the Appearance Panel and when cap assembly uses, is formed as roughly U word shape and covers forming the back face wall 730 of chamber and at least a portion of the inner face of sidewall 790 or whole inner faces of wall and being advisable.Now, lighting device (case intraoral illumination) is if 900 be disposed at and form roof 740 or the underside wall 780 of chamber, in the time making to reach sidewall 790 as the 1st wind path accessory 762 of cap assembly, compared with lighting device 900 being located to the situation of sidewall 790 inner faces, without the 1st wind path accessory 762 of the part that is provided with lighting device 900 is excised or arrange opening, therefore become easily as the shape of the Appearance Panel (the 1st wind path accessory 762) of cap assembly, can obtain heat insulating box, refrigerator, equipment cheaply.At this, can be formed as covering as the Appearance Panel of cap assembly the whole inner face side that form the roof 740 of chamber and at least a portion of back face wall 730 or wall.

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

At this, the relation of the filling rate to Vacuumed insulation panel 400 and the intensity of casing describes.Figure 15 is the figure that represents the density of hard polyurethane foams and the relation of thermal conductivity, Figure 16 represents the density of hard polyurethane foams and the figure of Deflection Modulus of Elasticity, Figure 17 is the figure of the relation of the stream thickness of the polyurethane while having represented to fill hard polyaminoester and the thermal conductivity of polyurethane, and Figure 18 is the figure of the relation of the stream thickness of the polyurethane while having represented to fill hard polyaminoester and the Deflection Modulus of Elasticity of polyurethane.Figure 15～Figure 18 is filling hard polyaminoester between two faces with predetermined gap (stream) and is making the experimental result under the model configuration body of its foaming, the face of one side of stream is the steel plate (profile that for example forms the heat insulating box 700 of Vacuumed insulation panel or refrigerator 1 is the coated steel plate of outer container 710) as the 1st parts, the face of the opposite side of stream is for example, as the resin of the 2nd parts (ABS(acrylonitrile, butadiene, cinnamic copolymerization resin that, interior case 750 uses), EPS(foamed plastic) etc. resin).

In Figure 15, transverse axis represents the density (kg/m of hard polyurethane foams ³), the longitudinal axis represents the thermal conductivity [W/(mK)] of hard polyurethane foams.In addition, Tu16Zhong, transverse axis represents the density (kg/m of hard polyurethane foams ³), the longitudinal axis represents the Deflection Modulus of Elasticity (MPa) of hard polyurethane foams.In Figure 17, transverse axis represents to fill the stream thickness (mm) of hard polyurethane foams, and the longitudinal axis represents the thermal conductivity [W/(mK)] of hard polyurethane foams.In Figure 18, transverse axis represents to fill the stream thickness (mm) of hard polyurethane foams, and the longitudinal axis represents the Deflection Modulus of Elasticity (MPa) of hard polyurethane foams.At this, fill the stream thickness table of hard polyurethane foams and be shown in the thickness of the hard polyurethane foams of the state of filling hard polyurethane foams in stream and foamed.

According to Figure 15, Figure 16, hard polyurethane foams thermal conductivity, Deflection Modulus of Elasticity in the time that density is larger is larger, and in density, more hour thermal conductivity, Deflection Modulus of Elasticity are less., density and thermal conductivity or density and Deflection Modulus of Elasticity are proportional relation substantially.

According to Figure 17, Figure 18, hard polyurethane foams thermal conductivity in the time that the stream thickness of filled polyurethane (or filling hard polyurethane foams and the thickness of the polyurethane of the state that foamed in stream) is narrower is larger, and in addition, Deflection Modulus of Elasticity is also larger.Therefore, the thickness of the polyurethane in stream after foaming is thicker, and thermal conductivity is less, and heat-proof quality is higher, but Deflection Modulus of Elasticity is less, and intensity is lower.Therefore, the thickness that reduce polyurethane is during with attenuate wall thickness, and Deflection Modulus of Elasticity increases, therefore no problem in intensity, but thermal conductivity becomes excessive, and heat-proof quality worsens, and therefore cannot make the thickness of polyurethane be less than to a certain degree (for example 15mm).

At this, at Figure 17, Tu18Zhong, if the stream thickness of filled polyurethane (or in stream the thickness of polyurethane after foaming) narrows, density increases, if density increases, thermal conductivity increases as shown in figure 15, and heat-proof quality worsens.At this, as shown in figure 17, for example, if the stream thickness of filled polyurethane (or in stream the thickness of polyurethane after foaming) becomes below predetermined thickness (11mm), thermal conductivity sharply increases, and heat-proof quality worsens.Hard polyurethane foams solidifies forming foaming between the 1st parts of polyurethane stream and the 2nd parts and bonding under the state of the 1st parts and the 2nd parts, now, polyurethane forms sandwich layer and forms the boundary layer that is called cortex in the both sides of this 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, Figure 23 A is the schematic diagram that is illustrated in the cross section while having filled hard polyurethane foams 701A between the 1st parts (interior case 750) and the 2nd parts (outer container 710), and Figure 23 B is the schematic diagram that is illustrated in the cross section while having filled hard polyurethane foams 701A while being folded with the 3rd parts (Vacuumed insulation panel 400) between the 1st parts (interior case 750) and the 2nd parts (outer container 710) between the 1st parts and the 3rd parts.

In Figure 23 A, the thermal wall that possesses polyurethane foam filled between the 1st parts and the 2nd parts for example, for example, is made up of the 1st parts (case 750 in), the 1st cortex 701B, sandwich layer 701C, the 2nd cortex 701D, the 2nd parts (outer container 710) successively.On the other hand, as shown in Figure 23 B, between the 1st parts (interior case 750) and the 2nd parts (outer container 710), during as the 3rd component configuration Vacuumed insulation panel 400, thermal wall is made up of the 1st parts (interior case 750), the 1st cortex 701B, sandwich layer 701C, the 2nd cortex 701D, the 3rd parts (Vacuumed insulation panel 400), the 2nd bonding agent the 715, the 2nd parts (outer container 710) successively.In addition, the 1st cortex 701B, sandwich layer 701C and the 2nd cortex 701D form hard polyurethane foams 701A.

Cortex is formed near the 1st parts or near the 2nd parts or near the 3rd parts, the stream thickness (thickness of polyurethane) of polyurethane is that the scope that uses of prior art is when about 20mm～30mm, the thickness of cortex is enough little with respect to the thickness of sandwich layer, to density, the impact of thermal conductivity etc. is very little, for example, if but the thickness of polyurethane is below predetermined thickness (11mm), the thickness of the cortex ratio shared with respect to the thickness of sandwich layer becomes large, to the density of polyurethane, thermal conductivity, the impact of Deflection Modulus of Elasticity sharply increases, density, thermal conductivity, it is large that Deflection Modulus of Elasticity sharply becomes.Therefore, heat-proof quality sharply worsens.In addition, as shown in figure 18, because the density of polyurethane rises, the Deflection Modulus of Elasticity of polyurethane also sharply rises.

Therefore, in prior art, if dwindle the thickness of polyurethane, Deflection Modulus of Elasticity increase, intensity improve, but the thermal conductivity of polyurethane rises, heat-proof quality worsens, and therefore cannot dwindle the thickness of polyurethane, and use in the scope of about 15mm～30mm.In prior art, taking polyurethane as main thermal insulation barriers, Vacuumed insulation panel is configured as the mode of auxiliary thermal insulation barriers, in the scope that therefore can not worsen in the heat-proof quality of polyurethane thermal insulation barriers, determine the thickness of polyurethane, even also guaranteed about 15mm～20mm in narrow part.

But, in the present embodiment, form thermal wall taking Vacuumed insulation panel as main thermal insulation barriers and by the mode that Vacuumed insulation panel obtains the intensity of casing, therefore the hard polyaminoester that disposes the part of Vacuumed insulation panel does not require heat-proof quality, for example, even if thereby be predetermined thickness (11mm, preferably 6mm) following also no problem, thinner Deflection Modulus of Elasticity rises, casing intensity improves, therefore better.Predetermined thickness is 11mm when following, and the thickness of cortex becomes large to the impact of sandwich layer, and thermal conductivity sharply increases, and heat-proof quality sharply reduces, and therefore in prior art, being difficult to make the thickness of hard polyurethane foams is below 11mm.In prior art, about the thickness of hard polyurethane foams, even if part is below 11mm making among a small circle predetermined value, being also difficult to make average thickness is below 11mm.And then if predetermined thickness is below 6mm, the thickness of cortex further increases the impact of sandwich layer, heat-proof quality worsens more, therefore in prior art, is difficult to use.But in the present embodiment, make Vacuumed insulation panel 400 there is the heat-proof quality of heat insulating box 700, though therefore the thickness of attenuate polyurethane use also no problem.Therefore, in the present embodiment, by the thickness of hard polyurethane foams being set as to 11mm following (being preferably less than 10mm), can increase the Deflection Modulus of Elasticity of hard polyurethane foams, the intensity (rigidity) of raising casing 700.In addition, if the thickness of hard polyurethane foams is set as below 6mm, can further increase the Deflection Modulus of Elasticity of hard polyurethane foams, therefore the intensity of casing 700 (rigidity) is further enhanced.

In addition, in the part that does not configure Vacuumed insulation panel 400, the thickness of polyurethane can for example, form compared with heavy back with the thickness of Vacuumed insulation panel (about 15mm～30mm), therefore the thickness of polyurethane can be guaranteed about 20mm～40mm, the scope (below the thickness 11mm of polyurethane) that can sharply not rise in the thermal conductivity of polyurethane is used, can for example, use in the little scope of the rising degree (slope) of the thermal conductivity of polyurethane (thickness of polyurethane is for example scope more than 15mm), also can guarantee that the heat-proof quality of polyurethane is below predetermined value even if therefore consider the uneven thickness of polyurethane.Therefore, can meet the intensity of heat insulating box 700 and the heat-proof quality both sides of heat insulating box 700.

At this, the 1st parts that use at the face of a side of polyurethane stream, use the resins such as resin (ABS(acrylonitrile, butadiene, cinnamic copolymerization resin that for example, interior case 750 uses) or EPS(foamed plastic)).The face of the opposite side of stream is used as the steel plate such as aluminium-vapour deposition film, the coated steel plate (PCM) of formation outer container 710 of the outsourcing material of Vacuumed insulation panel.

Next such as illustrate, at the thickness of the part that disposes Vacuumed insulation panel 400 (recess 440 or the 2nd recess 441 etc.), polyurethane with respect to the relation of ratio (thickness/(thickness+Vacuumed insulation panel thickness of polyurethane) of=polyurethane) and composite guide heating rate (thermal conductivity of the thermal wall that Vacuumed insulation panel and polyurethane are combined) of thickness (thickness of the thickness+polyurethane of Vacuumed insulation panel) of thermal wall that possesses polyurathamc and Vacuumed insulation panel 400.

Figure 19 be the polyurethane while representing that wall thickness (thickness between the inwall of wall) is fixed as 27mm thickness with respect to the ratio of the thickness of the thermal insulation barriers that Vacuumed insulation panel and polyurethane are combined, with the figure of the relation of composite guide heating rate.In Figure 19, the thickness that transverse axis represents polyurethane is with respect to the ratio of the thickness of the thermal insulation barriers that Vacuumed insulation panel and polyurethane are combined, the i.e. thickness of polyurethane/(thickness+Vacuumed insulation panel thickness of polyurethane), and the longitudinal axis represents composite guide heating rate (thermal conductivity that Vacuumed insulation panel and polyurethane are combined).At this, using the total of the thickness of the thickness of polyurethane and Vacuumed insulation panel, i.e. thickness thickness in wall of the thickness+Vacuumed insulation panel of polyurethane.

As shown in Figure 19, with respect to thickness in wall, hour, composite guide heating rate diminishes the thickness of polyurethane, and heat-proof quality improves.At this, composite guide heating rate represents the thermal conductivity of the composite component that polyurethane and Vacuumed insulation panel are combined.In figure, thickness is taking 0.3 for boundary's slope changes in the thickness/wall of polyurethane, and compared with being greater than 0.3 o'clock with thickness in the thickness/wall of polyurethane, the interior thickness of thickness/wall of polyurethane is approximately below 0.3 time, and slope is less, and the ratio of the reduction of composite guide heating rate is less.Figure is the experimental verification of thickness one timing in wall, and therefore in the thickness/wall of polyurethane, the ratio of thickness is less, and the thickness of polyurethane is less, otherwise the thickness of Vacuumed insulation panel is larger, and therefore the thickness of the Vacuumed insulation panel ratio shared with respect to thickness in wall is larger.,, with respect to thickness in wall, when the less thick of polyurethane, the thickness of Vacuumed insulation panel increases with respect to the ratio of the thickness of polyurethane.In figure, in the thickness/wall of polyurethane, thickness is approximately 0.6 place, the thickness of the Thickness Ratio Vacuumed insulation panel of polyurethane is large, therefore the thermal conductivity of polyurethane is larger on the impact of composite guide heating rate (Vacuumed insulation panel and polyurethane thermal conductivity altogether), and composite guide heating rate is large (heat-proof quality is poor) also.If dwindle the interior thickness of the thickness/wall of polyurethane, the thickness of Vacuumed insulation panel increases with respect to the ratio of the thickness of polyurethane, therefore compare the thermal conductivity of polyurethane, the thermal conductivity of Vacuumed insulation panel is larger on the impact of composite guide heating rate, result, along with thickness/(thickness of the thickness+Vacuumed insulation panel of polyurethane) of polyurethane diminishes, the thermal conductivity (composite guide heating rate) of the composite component that polyurethane and Vacuumed insulation panel combine reduces.At this, until the thickness of polyurethane/(thickness of the thickness+Vacuumed insulation panel of polyurethane) is approximately 0.3 o'clock, compare the thermal conductivity of polyurethane, the thermal conductivity of Vacuumed insulation panel is larger on the impact of composite guide heating rate, therefore the reduction ratio of composite guide heating rate is also larger, thickness/(thickness of the thickness+Vacuumed insulation panel of polyurethane) of polyurethane is less, and composite guide heating rate is less, and heat-proof quality significantly improves.

But, from the thickness of polyurethane with respect to the ratio of thickness in wall, the thickness of polyurethane/(thickness of the thickness+Vacuumed insulation panel of polyurethane) is less than approximately 0.3 o'clock, the slope of the reduction of composite guide heating rate changes, the slope of the reduction of composite guide heating rate diminish (ratio of the reduction of composite guide heating rate diminishes).This be considered to due to, the thickness of polyurethane is with respect to the ratio of thickness in wall, i.e. less thick in the thickness/wall of polyurethane, thereby with respect to the heat-proof quality of composite component (parts that polyurethane and Vacuumed insulation panel are combined), the heat-proof quality of Vacuumed insulation panel becomes overriding, and the impact of the heat-proof quality of the heat-proof quality of polyurethane on composite component diminishes.Therefore, in the present embodiment, in the thermal wall being formed by composite component (the polyurethane heat insulating member forming adjacent with Vacuumed insulation panel both sides), so that thickness is that mode below 0.3 is while setting the thickness of polyurethane in the thickness/wall of polyurethane, the ratio of the reduction of heat-proof quality diminishes, even if therefore the thickness of polyurethane or the thickness of Vacuumed insulation panel produce inequality, also can make the inequality of heat-proof quality less, therefore preferred.Otherwise, also thickness in the thickness/wall of Vacuumed insulation panel can be set as more than 0.7.

Therefore,, so that thickness is, when approximately the mode below 0.3 is set the thickness of polyurethane, can reduce composite guide heating rate in the thickness/wall of polyurethane, the heat-proof quality of composite component is largely increased.In addition, if the inequality (or inequality of the thickness of Vacuumed insulation panel) of the thickness of consideration polyurethane is set, the interior thickness of the thickness/wall of polyurethane is in the scope below 0.3, even if the thickness of the thickness of polyurethane, Vacuumed insulation panel produces uneven, also can suppress the reduction of the heat-proof quality of composite component, and can suppress the inequality of the composite guide heating rate of composite component, therefore can obtain high, the high performance thermal wall of reliability, heat insulating box, refrigerator, equipment etc.

Figure 20 is that the volume ratio shared with respect to the volume in space in wall 315 that represent Vacuumed insulation panel 400 is the filling rate of Vacuumed insulation panel, the figure of the relation of the deflection of heat insulating box when to heat insulating box 700 imposed loads (load).In Figure 20, transverse axis represents the filling rate of Vacuumed insulation panel, the deflection that the longitudinal axis represents heat insulating box.At this, the filling rate of Vacuumed insulation panel is the ratio (ratio) of Vacuumed insulation panel 400 volume shared with respect to the volume in the space 315 in wall, the deflection of heat insulating box is in the heat insulating box of such as refrigerator 1 grade, to have under the state of door on the side apart from casing the height and position of approximately 1/4 left and right along general horizontal direction (laterally, observing when front openings portion in front is left and right directions) upper end position of the sidewall 790 of casing 700 while having applied predetermined load is in the result of calculation of the deflection of left and right directions (laterally), if the deflection when filling rate of Vacuumed insulation panel 400 is 20% is 1.Figure 20 is the coating rate that makes Vacuumed insulation panel (for example 65%), polyurethane density (for example 60kg/m ³), the wall thickness (such as 30mm) that is added of the thickness of thickness (such as 28mm), outer container and the interior case of the Deflection Modulus of Elasticity (such as 15MPa) of the Deflection Modulus of Elasticity (such as 9MPa) of polyurethane, Vacuumed insulation panel, composite component etc. fix and the varied in thickness that the makes Vacuumed insulation panel result during with the filling rate of change Vacuumed insulation panel.

In Figure 20, the filling rate of Vacuumed insulation panel is larger, and box deformation amount is less.This be considered to due to, the Deflection Modulus of Elasticity of Vacuumed insulation panel is larger than the Deflection Modulus of Elasticity of polyurethane, thereby follow the volume of Vacuumed insulation panel to increase with respect to the ratio of the polyurethane volume in heat insulating box, it is large that the impact of the Deflection Modulus of Elasticity of Vacuumed insulation panel becomes, and the rigidity of casing 700 increases.The filling rate of Vacuumed insulation panel 400 is 40% when above, and the reduction ratio of the deflection of casing becomes minimum, even if the filling rate of Vacuumed insulation panel increases, box deformation amount also changes hardly.This be considered to due to, Vacuumed insulation panel 400 approaches saturated for the influence degree of casing intensity (distortion of casing) substantially.

The Deflection Modulus of Elasticity of Vacuumed insulation panel 400 is larger than hard polyurethane foams, therefore by increasing the volume ratio (ratio) (increase the filling rate of Vacuumed insulation panel) shared with respect to the volume in space 315 of Vacuumed insulation panel 400, can dwindle the deflection of heat insulating box 700, therefore can improve the casing intensity of heat-proof quality, increase heat insulating box 700 or refrigerator 1 or the equipment of heat insulating box 700.Now, increase filling rate if increase the thickness of Vacuumed insulation panel 400, in the effect that just can improve in the intensity that realizes casing, improve heat-proof quality.At this, can increase by increasing the thickness of Vacuumed insulation panel the filling rate of Vacuumed insulation panel, also can increase by increasing the surface area of Vacuumed insulation panel 400 filling rate of Vacuumed insulation panel with respect to the ratio (the coating rate of Vacuumed insulation panel) of the surface area of casing 700, now also can increase the intensity of casing, and, by increasing the coating rate of Vacuumed insulation panel 400, can increase the filling rate of Vacuumed insulation panel.In addition, if increase the coating rate of Vacuumed insulation panel 400, the configuration scope of Vacuumed insulation panel (configuration position) increases, and wall thickness that can attenuate heat insulating box 700, therefore can make storeroom internal volume increase the amount of wall thickness reduction.

In the present embodiment, for example, the at least a portion in the space 315 between the interior case 750 of a part that forms the outer container 710 of profile of heat insulating box and the inwall of the storeroom of formation heat insulating box possesses Vacuumed insulation panel 400, the filling rate that makes the Vacuumed insulation panel 400 in space 315 is more than 40%, and to make Vacuumed insulation panel 400 be more than 60% with respect to the area ratio (coating rate) of the surface area of outer container 710, thereby can obtain that heat-proof quality is high, the casing intensity heat insulating box that also large and reliability is high, refrigerator, equipment etc.At this, in the present embodiment, be configured to the wall intensity of being born heat insulating box 700 by the high Vacuumed insulation panel 400 of the Deflection Modulus of Elasticity hard polyurethane foams more used than existing heat insulating box, therefore can meet casing intensity and heat-proof quality simultaneously, and can attenuate wall thickness, therefore storeroom internal volume also can increase.

The heat insulating box 700 of present embodiment is by the filling rate of Vacuumed insulation panel 400 higher than hard polyaminoester bending strength being set as to predetermined value above (or in preset range) or the filling rate of Vacuumed insulation panel 400 and coating rate both sides being set as to predetermined value above (or in preset range), can meet heat-proof quality and casing intensity and wall thickness that can attenuate heat insulating box 700 simultaneously.Therefore, the appearance and size that need not change heat insulating box 700, refrigerator 1 can expand the internal volume in storeroom, can be increased in collecting article, reserve that the inside of heat insulating box 700 or refrigerator 1 or equipment can be stored.In addition, when wall strength decreased, can there is heat insulating box 700 and be out of shape, be for example located at inner shelf 80 offset track portions and fall or the problem such as the sliding variation of the storeroom of drawer type (or door or box body or shutter door etc. of drawer type).But in the present embodiment, due to the filling rate of Vacuumed insulation panel 400 and/or coating rate are set as to predetermined value above (in preset range), therefore wall thickness that can attenuate heat insulating box 700, and can improve casing intensity and heat-proof quality, therefore can suppress the generation of following situation: shelf 80 offset track portions and falling, or the sliding variation of the storeroom of drawer type (or door or box body or shutter door etc.), cause reliability to reduce.

In addition, to make the filling rate of the Vacuumed insulation panel 400 in space 315 be below 90% to the heat insulating box 700 of present embodiment 1.According to the technological thought of above-mentioned present embodiment, it is desirable to space 315 interior is all Vacuumed insulation panel 400.But, as illustrated at Figure 11 etc., wall 730 is provided with protuberance 450 or jut 910 overleaf, in addition make the orbit portion 755 that is formed at interior case 750 arrange highlightedly in space 315, in addition by heat insulating box 700 during for refrigerator 1 for example, in wall, in space 315, also to be configured for the pipe 720 of storage wire harness, therefore be difficult to make the filling rate of Vacuumed insulation panel 400 to exceed 90%, above-mentioned wire harness is by connecting the compressor 12 carrying in the Machine Room 1A of heat insulating box 700, the control device 30(that controls storage in substrate chamber 31 for example controls the device of the rotating speed of compressor etc.) etc. distribution class boundling form.In addition,, when heat insulating box 700 is for example applied to refrigerator 1, in space 315, also to configure refrigerant piping 725 etc.Therefore, if will exceed 90% ground configuration Vacuumed insulation panel 400 in space 315, just need to the Vacuumed insulation panel 400 of the form fit of distribution class 720, refrigerant piping 725, orbit portion 755 etc., it is complicated that the shape of Vacuumed insulation panel 400 becomes, thereby the moulding of Vacuumed insulation panel 400 (or formation) becomes difficulty, therefore the filling rate of Vacuumed insulation panel 400 is set as below 90%.

In addition, the problem deforming in order to suppress the strength decreased of heat insulating box 700, need to make outer container 710 and interior case 750 and Vacuumed insulation panel 400 bonding and possess adhesive strength, and it is more, complex-shaped at interior case 750, such as, such as, situation for keeping orbit portion 755, other accessories (lighting device 900 or mist device 200 or partition wall 24 etc.) of being located at the shelf 80 in storeroom (refrigerating chamber 2) to be installed.Therefore,, even if be easy to Vacuumed insulation panel 400 to bond to outer container 710 sides by PUR or double faced adhesive tape grade in an imperial examination 2 bonding agents, be also difficult to make Vacuumed insulation panel 400 bond to complex-shaped interior case 750 sides and obtain adhesive strength.

But, when bonding agent using hard polyurethane foams between interior case 750 and Vacuumed insulation panel 400 uses, in can making it mobile with two-phase state in space 315, fill, foaming, also can by polyurethane, interior case 750 and Vacuumed insulation panel 400 be bonded together without problems while there are protuberance 450, jut 910, orbit portion 755, other accessories even therefore interior in space 315.Certainly, also can between outer container 710 and Vacuumed insulation panel 400 or between outer container 710 and interior case 750, fill hard polyurethane foams as bonding agent.Now, if do not fill the not filling part (being space) of hard polyurethane foams in the interior generation of heat insulating box 700, the heat-proof quality of heat insulating box 700 can reduce.Therefore, in the heat insulating box 700 of present embodiment, for example need to guarantee, for filling the required predetermined gap to a certain degree of hard polyurethane foams (about 1mm above, more than preferred about 3mm), therefore the filling rate of the Vacuumed insulation panel 400 in space 315 can be, below 90%, to be preferably below 80%.

But if the filling rate of the Vacuumed insulation panel 400 in space 315 is increased, the filling rate of the hard polyurethane foams in space 315 will reduce.Therefore, the thickness of the polyurethane between outer container 710 and interior case 750 reduces, and may cause the casing strength decreased of heat insulating box 700.But the heat insulating box of present embodiment 700, by using all Vacuumed insulation panels 400 better than polyurethane of heat-proof quality, bending rigidity, can suppress the reduction of casing intensity.In addition, in the present embodiment, technological thought is mainly to bear heat insulating function and intensity by the little Vacuumed insulation panel 400 of thermal conductivity, therefore as shown in figure 20, be more than 40% by making the filling rate of Vacuumed insulation panel, even if the loading of hard polyaminoester reduces, also can improve the intensity of casing 700.In addition, as shown in figure 19, by the thickness (increasing the filling rate of Vacuumed insulation panel) of thickening Vacuumed insulation panel 400, can dwindle the composite guide heating rate of the compound heat-insulation part that Vacuumed insulation panel and hard polyurethane foams are combined, therefore the heat-proof quality of casing 700 also improves.

At this, increase Deflection Modulus of Elasticity (bending rigidity) if increase the density of hard polyurethane foams, the heat-proof quality of hard polyurethane foams self can reduce, but be more than predetermined value by the coating rate and the filling rate that make Vacuumed insulation panel 400, the impact of the reduction of the heat-proof quality of polyurethane can diminish and not become problem.In the heat insulating box 700 of present embodiment, as shown in figure 16, by make hard polyurethane foams density ratio prior art greatly, be for example greater than 60kg/m ³for example, more than the large 15MPa of Deflection Modulus of Elasticity that the Deflection Modulus of Elasticity that can make hard polyurethane foams is the hard polyurethane foams that uses than existing heat insulating box (approximately 6～10MPa), can also improve the casing intensity of the part that does not configure Vacuumed insulation panel 400.Therefore, the equipment such as the heat insulating box 700 of present embodiment, refrigerator 1, showcase, hot water supply device, be more than 70% by making the filling rate of Vacuumed insulation panel 400 be more than 40%, making the laterodorsal coating rate of Vacuumed insulation panel, the strength decreased causing because of the reduction of the filling rate of hard polyurethane foams can be suppressed, the crooked distortion that heat insulating box 700 causes because tolerating the weight of collecting article can also be suppressed.; by increasing the filling rate of Vacuumed insulation panel 400; can improve the intensity of heat insulating box 700; in addition; can obtain good heat-proof quality, therefore can obtain the high and energy-conservation heat insulating box that possesses Vacuumed insulation panel of reliability, possess Vacuumed insulation panel refrigerator, possess Vacuumed insulation panel showcase, possess Vacuumed insulation panel hot-water supply, possess equipment of Vacuumed insulation panel etc.

In addition, the density adjustment of hard polyurethane foams, for example can be by making the amount of the stoste that is injected into the hard polyurethane foams in space 315 fill manyly than prior art (lengthen injection length or strengthen injection pressure) and density is adjusted greatlyr or less.In addition, the Deflection Modulus of Elasticity of hard polyurethane foams increases substantially pro rata with the size of density as shown in figure 16, therefore increase density and just can increase Deflection Modulus of Elasticity, and Deflection Modulus of Elasticity is when larger, gear housing rigidity increases, therefore preferred, but the Deflection Modulus of Elasticity of polyurethane is preferably below 150MPa.If the Deflection Modulus of Elasticity of hard polyurethane foams is greater than 150MPa, the density of hard polyurethane foams becomes excessive, can cannot be foamed into spongy and solidify, heat-proof quality sharply reduces, therefore thereby to be that 150MPa can suppress the reduction of heat-proof quality when following preferred for the Deflection Modulus of Elasticity of hard polyurethane foams, can obtain high performance heat insulating box.

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

(1) average wall thickness that use the total thickness of slab of outer container 710 and interior case 750 following for about 2mm, to comprise the thickness of slab of outer container 710 and the heat insulating box 700 of interior case 750 thicknesss of slab is the heat insulating box below the above about 40mm of about 20mm (at this, the average distance (thickness in wall) of having removed the wall thickness direction in the space 315 of the thickness of slab of outer container 710 and interior case 750 is about 18mm～about 38mm).

(2) thickness of Vacuumed insulation panel 400 is about 10mm～about 30mm, and the average flow path width (polyurethane stream thickness) that disposes the wall thickness direction of the hard polyurethane foams in for example, space 315 in the wall of part (recess 440 or the 2nd recess 441) of Vacuumed insulation panel is 1mm above (preferably more than 3mm), 11mm following (preferably 6mm is following).

(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 that the power consumption under 200L～600L level, predetermined condition is the following degree of about 60W.

The heat-proof quality of this refrigerator 1 is by setting the size, the thickness that make the filling rate of Vacuumed insulation panel 400 and coating rate in predetermined scope and select Vacuumed insulation panel 400 for, make Vacuumed insulation panel 400 become overriding with respect to the heat-proof quality of heat insulating box, the casing intensity of heat insulating box, thereby the thermal conductivity of Vacuumed insulation panel 400 hour, thereby the composite guide heating rate that can reduce heat insulating box is preferred, is preferably 0.0030W/(mK) below.If the thermal conductivity of Vacuumed insulation panel 400 exceedes 0.0030W/mK, wall thickness reduces the impact of heat-proof quality is become to large, and heat-proof quality worsens, and power consumption amount increases.Therefore, in the present embodiment, be 0.0030W/(mK by making the thermal conductivity of Vacuumed insulation panel 400) below, the impact that the heat-proof quality relative with attenuate wall thickness reduces can be suppressed.In addition, the thermal conductivity of Vacuumed insulation panel 400 is the smaller the better, but for thermal conductivity is reduced to 0.001W/(mK) spent cost significantly increases, the thermal conductivity that therefore uses Vacuumed insulation panel 400 is 0.0012W/(mK) above parts.If the thermal conductivity of Vacuumed insulation panel 400 is 0.0019W/(mK) above 0.0025W/(mK) below, just little approximately 10 times than the thermal conductivity of hard polyurethane foams, therefore the heat-proof quality of heat insulating box 700 is especially good compared to existing technology, can meet product specification.Therefore, Vacuumed insulation panel 400 uses thermal conductivity for about 0.0012W/(mK) above 0.0030W/(mK) following (being preferably about 0.0019W/(mK) above 0.0025W/(mK) below) parts.

As an example of the heat insulating box 700 of embodiment of the present utility model, in the relation of the box deformation amount of the Deflection Modulus of Elasticity of the filling rate of wall thickness shown in table 1 and Vacuumed insulation panel 400, hard polyurethane foams, heat insulating box 700.The item of table 11 is existing specification, is that wall thickness is that the filling rate of 40mm, Vacuumed insulation panel 400 is 20%, the result of the Deflection Modulus of Elasticity of the polyurethane of filling between interior case 750 and Vacuumed insulation panel 400 while being 9MPa.At this, the Deflection Modulus of Elasticity of Vacuumed insulation panel 400 uses the parts of 20MPa.According to the item 1 and 2 of table 1, the filling rate of Vacuumed insulation panel 400 is 20%, the Deflection Modulus of Elasticity of polyurethane is while being 9MPa, if make the wall thickness of heat insulating box 700 be thinned to 30mm from 40mm, and casing strength decreased.Therefore, known as shown in item 3, in the situation that making wall thickness reduction to 30mm, if the filling rate of Vacuumed insulation panel 400 is increased to more than 40%, although box deformation amount is than a 1(prior art) slightly large, be reduced to the prior art with item 1() equal degree.

As shown in the item 4 of table 1, even the item 1 by the wall thickness of heat insulating box 700 from existing 40mm(table 1) be thinned to 30mm, as long as it is more than 40% making the filling rate of Vacuumed insulation panel 400 and the Deflection Modulus of Elasticity of polyurethane is 15Mpa above (item 4 of table 1), just can make box deformation amount less than prior art (item 1), the casing intensity that therefore can make heat insulating box 700 is more than existing parts (item 1)., for example, even if reduce wall thickness (reducing to 30mm from 40mm), as long as more than the Deflection Modulus of Elasticity of the filling rate of Vacuumed insulation panel 400 and polyurethane is set as to predetermined value, just can reduce casing intensity and improve heat-proof quality.Therefore, in the present embodiment, by using parts more than Deflection Modulus of Elasticity 20MPa as Vacuumed insulation panel 400, and more than the filling rate of Vacuumed insulation panel 400 is set as to be set as 15MPa more than 40%, by the Deflection Modulus of Elasticity of hard polyurethane foams, for example, even if the wall thickness of attenuate heat insulating box (being thinned to 30mm from 40mm), also can improve the intensity of heat insulating box 700 compared to existing technology.

In addition, form the outsourcing material (exterior film) of the profile of Vacuumed insulation panel 400, compare aluminium foil film and preferably use aluminium-vapour deposition film.For the heat leak (the so-called heat bridge that heat is conducted to the back side and leaked from the surface of Vacuumed insulation panel 400 via the outsourcing material of Vacuumed insulation panel 400) that suppresses to occur along the outsourcing material of Vacuumed insulation panel 400, as the outsourcing material of Vacuumed insulation panel 400, compare aluminium foil film, preferably the aluminium-vapour deposition film that is difficult to produce heat bridge is used as outsourcing material (exterior film).

In addition, the mensuration of the Deflection Modulus of Elasticity of the hard polyurethane foams in present embodiment 1, thermal conductivity, density, for example, for example, measure by the hard polyurethane foams that cuts pre-sizing (more than 100 × 100 × 5mm).In the part that disposes Vacuumed insulation panel 400, from left and right side, each face of the back side, end face, these five faces of bottom surface part of disposing Vacuumed insulation panel cuts multiplely, calculates its mean value.(while only cutting 1 position, carry out at 1 position many places mensuration etc. substitute be advisable).In the time that door also disposes Vacuumed insulation panel, opposite house is also measured density, Deflection Modulus of Elasticity, the thermal conductivity of polyurethane.In addition, in the part that does not configure Vacuumed insulation panel 400, also each face of left and right side, the back side, end face, these five faces of bottom surface is cut multiplely, and calculate its mean value.In the present embodiment, be all from inferring that the place that density or Deflection Modulus of Elasticity are larger cuts and measures in any case.In addition, hard polyurethane foams can not be cut into pre-sizing in the time there is distribution accessory 720 of refrigerant piping 725, lead-in wire etc. etc. etc., be advisable as the position of the hard polyurethane foams that can cut pre-sizing in the position that approaches center.

In the present embodiment, to each of left surface, right flank, the back side, end face, bottom surface or these six faces of door, mensuration disposes the part of Vacuumed insulation panel 400 and density or the Deflection Modulus of Elasticity of polyurethane of the part of configuration, and it is more than predetermined value making the density of polyurethane or Deflection Modulus of Elasticity.Can be by adjusting the free foaming density, thickness, the wall thickness etc. of Vacuumed insulation panel of polyurethane, more than the density at the polyurethane of sandwiched between Vacuumed insulation panel 400 and interior case 750 or between Vacuumed insulation panel 400 and outer container 710 or between outer container 710 and interior case 750 or Deflection Modulus of Elasticity are set as to predetermined value.

At this, in the present embodiment, in left and right side, the back side, end face, bottom surface or these six faces of door, more than being set as predetermined value for each density, Deflection Modulus of Elasticity that disposes the polyurethane of the part of Vacuumed insulation panel 400 to major general, more than also can being set as predetermined value for each density, Deflection Modulus of Elasticity that does not configure the polyurethane of the part of Vacuumed insulation panel 400 to major general in addition.At this, in left and right side, the back side, end face, bottom surface or these six faces of door, if set for for each face, to make polyurethane density, Deflection Modulus of Elasticity be more than predetermined value, also improves in the part intensity that does not configure Vacuumed insulation panel 400.In addition, owing to can obtaining intensity at each independent face, therefore can only set the part of needs for high strength, can obtain heat insulating box, refrigerator, equipment that low cost and reliability are high.In addition, set that to make left and right side, the back side, end face, bottom surface or the door density of these six faces or the mean value of Deflection Modulus of Elasticity be above (the density 60kg/m of predetermined value for ³above, more than Deflection Modulus of Elasticity 15MPa) time, can guarantee the intensity of whole casing therefore can obtain heat-proof quality is high, reliability is high heat insulating box, refrigerator, equipment.

In addition, for coating rate, the filling rate of Vacuumed insulation panel 400, also in left and right side, the back side, end face, bottom surface or these six faces of door set that to make each or multiple face coating rate, filling rate be altogether more than predetermined value for, owing to can obtaining intensity, heat-proof quality at each independent face, therefore can only set the part of needs for high strength, can obtain low cost, height is heat insulation, reliability is high heat insulating box, refrigerator, equipment.In addition, set for and make left and right side, the back side, end face, bottom surface or these six faces entirety of door for predetermined value is when above, can guarantee whole casing intensity, improve the heat-proof quality of whole casing, therefore can obtain heat-proof quality is high, reliability is high heat insulating box, refrigerator, equipment.

Above, in the heat insulating box 700 of present embodiment, make the coating rate of Vacuumed insulation panel 400 be greater than predetermined value (60%) (it is more than 70% making the laterodorsal coating rate of Vacuumed insulation panel 400).In addition, make the filling rate of Vacuumed insulation panel 400 also for predetermined value (40%) is above to reduce the loading of hard polyurethane foams, therefore heat-proof quality and the casing intensity of heat insulating box can be guaranteed, wall ratio prior art thin of heat insulating box 700 can be made simultaneously.Therefore, energy-conservation thereby heat-proof quality is improved, and can make compared to existing technology the internal volume in storeroom increase the amount of wall thickness reduction, thus heat insulating box 700, refrigerator 1, showcase, the equipment that internal volume efficiency is good can be provided.; according to embodiment of the present utility model; the appearance and size that does not change the equipment such as heat insulating box 700 or refrigerator 1 or showcase increases internal volume (for example internal volume of storeroom 2～6) with regard to comparability prior art, and therefore comparability prior art increases the collecting article that the inside of heat insulating box 700 or refrigerator 1 can be stored.Thus, can obtain the equipment such as easy to use, the energy-conservation heat insulating box of user 700, refrigerator 1, showcase.Otherwise, for example, if make internal volume (internal volume of storeroom 2～6) and prior art equal, can dwindle appearance and size, therefore can obtain the equipment such as energy-conservation and compact heat insulating box 700, refrigerator 1, showcase, hot-water supply.

In addition, the heat insulating box 700 shown in present embodiment, the mode of refrigerator 1, shape are only an example.For example, also the reserve accommodation space of heat insulating box 700 can be formed to four accommodation spaces (storeroom) by 3 cross septation plate zonings at above-below direction.In addition, for example also the reserve accommodation space of heat insulating box 700 also further can be used to vertical demarcation strip zoning by 3 cross septation plate zonings, thereby form five accommodation spaces (storeroom).By increasing the quantity of demarcation strip 24, can further improve the intensity of heat insulating box 700.; increase the quantity of demarcation strip 24 to increase the quantity of receiving room, storeroom; can obtain the effect that improves casing intensity by demarcation strip; for example, even if thereby the average thickness of the hard polyurethane foams of the part that attenuate is covered by Vacuumed insulation panel 400 (space 315 between Vacuumed insulation panel 400 and interior case 750) (11mm below, is preferably less than 10mm, more preferably 6mm is following) also can be guaranteed enough casing intensity.Therefore, the appearance and size that does not change heat insulating box 700 just can further increase the internal volume of storeroom, can further increase the collecting article that the inside of heat insulating box 700 can be stored.

In addition in the present embodiment, about the internal structure of demarcation strip 24, can be the formation same with heat insulating box 700.; inner space at demarcation strip 24 configures Vacuumed insulation panel 400 and fills hard polyurethane foams; but hard polyurethane foams, therefore can be thinner as long as bonding agent, for example can for about 11mm below, be preferably less than 10mm, more preferably below about 6mm.At this, more in the situation that does not configure pipe arrangement 725, distribution 720 etc. in demarcation strip 24 as heat insulating box 700, therefore in this case, although also can by Vacuumed insulation panel 400 with respect to the filling rate of demarcation strip 24 be set as with heat insulating box 700 equal more than 40% below 90%, but about partition wall 24, can, at roughly whole the configuration Vacuumed insulation panel 400 of the size of demarcation strip 24 (space in demarcation strip 24), therefore the filling rate of Vacuumed insulation panel 400 can be brought up to more than approximately 40% below 95%.In addition, the Deflection Modulus of Elasticity of hard polyurethane foams is that 15MPa is above, density is greater than 60kg/m ³be advisable.By also configuring like this Vacuumed insulation panel 400 and filling rate is set in to preset range in demarcation strip 24, can further improve the heat-proof quality of heat insulating box 700.

In the present embodiment, in the case of the heat insulating box or thermal wall that possess Vacuumed insulation panel, consider assembleability and Vacuumed insulation panel 400 is directly pasted to outer container 710 by the 2nd bonding agent different from polyurathamc such as PUR or double faced adhesive tape, between Vacuumed insulation panel 400 and interior case 750, conduct is filled hard polyurethane foams taking the bonding bonding agent as main purpose, but spacers that also can be formed by resins such as EPS in the interior configuration in space 315 being formed between outer container 710 and interior case 750 etc. and Vacuumed insulation panel 400 being floated between interior case 750 and outer container 710 are configured, and filling hard polyurethane foams between Vacuumed insulation panel 400 and outer container 710 and between Vacuumed insulation panel 400 and interior case 750.In addition, also Vacuumed insulation panel 400 directly can be pasted to interior case 750 and filled polyurethane foam between Vacuumed insulation panel 400 and outer container 710 by PUR or double faced adhesive tape grade in an imperial examination 2 bonding agents.

At this, in the time Vacuumed insulation panel 400 being floated over by spacer etc. be configured between outer container 710 and interior case 750, can the inner face side of outer container 710 (space between outer container 710 and Vacuumed insulation panel 400) spacer is set and at for example condensation pipe arrangement of spacer spatial placement refrigerant piping 725().Refrigerant piping 725 is also the condensation pipe arrangement that makes the flow of refrigerant of the HTHP that the compressor 12 from being disposed in the 1A of Machine Room discharges, via the tube wall of refrigerant piping 725 and outer container 710 under the effect of heat conduction etc., make at the interior mobile cold-producing medium of pipe arrangement 725 cooling and make condensation of refrigerant by the ambient air of pipe arrangement 725, thereby use as condensation pipe arrangement.In addition, the heat insulating box 700 of present embodiment has the resinous spacer of the thickness more than diameter of refrigerant piping 725 with the inwall setting of the outer container 710 of the nonoverlapping position of refrigerant piping 725 (not position) in opposite directions, and make Vacuumed insulation panel 400 paste spacer, so, refrigerant piping 725 is being pasted after outer container 710 ground configurations, the spacer that is pasted with Vacuumed insulation panel 400 directly can be pasted to outer container 710 with double faced adhesive tape etc. in the mode that covers refrigerant piping 725, be easy to manufacture.The heat insulating box 700 of present embodiment is configured to Vacuumed insulation panel 400 to separate predetermined interval with interior case 750, and Vacuumed insulation panel 400 is configured to separate predetermined interval with outer container 710, therefore become Vacuumed insulation panel 400 and be embedded in the formation in hard polyurethane foams, heat-proof quality is improved.

As mentioned above, in the present embodiment, heat insulating box 700 can be between outer container 710 and interior case 750 the interior foam filled so that Vacuumed insulation panel 400 in space 315 be embedded in hard polyurethane foams, in this situation, between outer container 710 and Vacuumed insulation panel 400, exist the situation of condensation pipe arrangement 725 more, but can make Vacuumed insulation panel 400 and outer container 710 there is predetermined distance by being configured to resinous spacers such as utilizing EPS etc., configure Vacuumed insulation panel 400.

In addition, Vacuumed insulation panel 400, in the time becoming high temperature, easily absorbs gas around, can cause inner vacuum reduction, thermal conductivity to worsen.The in the situation that outside summer etc., temperature degree being high, the environment temperature (ambient air temperature) of outer container 710 uprises, the temperature of outer container 710 self also may uprise, in addition, the pipe arrangement 725 using as condensation pipe arrangement also becomes high temperature, therefore from guaranteeing the angle of reliability of Vacuumed insulation panel 400, preferably make Vacuumed insulation panel 400 away from outer container 710, refrigerant piping (condensation pipe arrangement) 725.By making Vacuumed insulation panel 400 away from outer container 710, refrigerant piping (condensation pipe arrangement) 725, can suppress Vacuumed insulation panel 400 because of temperature rise cause deteriorated, if therefore make Vacuumed insulation panel 400 float with the wall away from outer container 710 or refrigerant piping 725 by spacer etc., just can suppress the reduction of heat-proof quality, heat insulating box 700, refrigerator 1 that reliability is high can be provided for a long time.

In addition, Vacuumed insulation panel 400 causes inner vacuum to decline because absorbing gas (air etc.) around sometimes, thermal conductivity worsens, but the resinous spacers such as EPS are pasted to the ground such as outer container 710 in hard polyurethane foams, bury Vacuumed insulation panel 400 underground by being configured to, can reduce the amount of the gas (air etc.) of the surrounding of Vacuumed insulation panel 400, therefore can suppress Vacuumed insulation panel 400 and absorb gas (air etc.) around, can suppress the deteriorated of the Vacuumed insulation panel 400 that causes because of the reduction of vacuum, can the high heat-proof quality of long term maintenance, and can provide the heat insulating box 700 that reliability is high, refrigerator 1, equipment etc.

Especially, in the heat insulating box 700 of present embodiment, hard polyurethane foams that hard polyurethane foams uses density ratio existing heat insulating box to use high (density is greater than 60kg/m ³), therefore the bubble in hard polyurethane foams can correspondingly reduce the amount that density increases, and can reduce the amount (air capacity) of the gas in bubble.Therefore, so that the mode that the surrounding of Vacuumed insulation panel 400 is buried underground or covered by hard polyurethane foams is when filling or configuring, can reduce the amount of the gas (air etc.) of the surrounding of Vacuumed insulation panel 400, therefore (density of polyurethane is larger can to suppress the reduction of the vacuum of Vacuumed insulation panel 400, space number in polyurethane is fewer, and the air capacity in polyurethane is fewer).Especially in the time of the thinner thickness of polyurethane (be for example below 11mm time), Vacuumed insulation panel 400 easily makes the gases such as the air that around waits from polyurethane enter, and the gas flow of surrounding that the density that therefore increases polyurethane reduces Vacuumed insulation panel 400 is larger for the effect of the degradation inhibiting of Vacuumed insulation panel 400.Therefore, can further suppress the deteriorated of Vacuumed insulation panel 400, heat insulating box 700, refrigerator 1, equipment that reliability is high can be provided for a long time.

In addition, be illustrated as example condensation pipe arrangement 725 is disposed to heat insulating box 700 in space 315 in the present embodiment, but can certainly in hard polyurethane foams, bury Vacuumed insulation panel 400 underground in condensation pipe arrangement 725 not being disposed to the heat insulating box 700 in space 315.Can reduce the amount of the gas of the surrounding of Vacuumed insulation panel 400, therefore can suppress the deteriorated of Vacuumed insulation panel 400, the heat insulating box 700 that reliability is high can be provided for a long time.

At this, do not form heat insulating box 700, the situation of refrigerator 1 etc. of the formation of orbit portion (track or recess etc. that the drawer of drawer type storeroom is used) 755, interior case 750 when being easy to utilize bonding agent or double faced adhesive tape etc. directly to paste the shape of Vacuumed insulation panel 400 at interior case 750, all or part of of Vacuumed insulation panel 400 can be disposed to interior case 750 sides yet.

At this, in the case of Vacuumed insulation panel 400 directly being pasted by PUR or double faced adhesive tape etc. the heat insulating box 700 of formation of interior case 750 sides, can provide with the Vacuumed insulation panel of less amount 400 internal volume efficiency heat insulating box 700, the refrigerator 1 better than prior art of energy-conservation and storeroom as shown in the embodiment.; the in the situation that of rectangular-shaped or heat insulating box cylindraceous roughly 700; in the surface area ratio of outer container 710, the surface area of case 750 is large; therefore in the time pasting Vacuumed insulation panel 400; Vacuumed insulation panel 400 specific viscositys that are bonded at interior case 750 surfaces are few at the Vacuumed insulation panel 400 on outer container 710 surfaces, therefore can obtain heat insulating box, refrigerator, showcase, hot water supply device, equipment that low cost and heat-proof quality are good.In addition, for example, in the time pasting the Vacuumed insulation panel 400 of formed objects, in the bight of rectangular-shaped heat insulating box 700 (for example, as the bight of the back side of heat insulating box 700 and the connecting portion of side, or the bight of end face and side, or the bight at end face and the back side etc.), the gap (for example, gap between the Vacuumed insulation panel 400 of the Vacuumed insulation panel 400 of end face and adjacent side or distance) of 400 of the Vacuumed insulation panels of bight place wall adjacent one another are, in the time that Vacuumed insulation panel 400 is disposed to outer container 710 side, it is large when Vacuumed insulation panel 400 is disposed to interior case 750 side.; by Vacuumed insulation panel 400 being disposed to interior case 750; compared with when the Vacuumed insulation panel of formed objects 400 is disposed to outer container 710; can dwindle the gap forming each other at adjacent Vacuumed insulation panel 400; make the heat waste causing because of heat leak correspondingly reduce the amount that gap dwindles, heat insulating box 700, refrigerator 1, hot water supply device, showcase, equipment that heat-insulating efficiency is good can be provided.

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

In the time manufacturing this shutter door, by Vacuumed insulation panel 400 in advance by profile parts that is adhesively fixed such as the 2nd bonding agents, the raw material of liquid hard polyurethane foams is injected to the space between space, outside parts and the inner part between Vacuumed insulation panel and inner part, so that the mode that profile parts, Vacuumed insulation panel 400, inner part can be integrally formed foams, thereby can in door inner space, fill the hard polyurethane foams as foaming heat insulation part.Now, as long as the thickness of hard polyurethane foams is also the intensity having as bonding agent, can be for the above preferably 3mm of 1mm be above and 11mm is following (be preferably less than 10mm, more preferably 6mm is following).

In addition, for shutter door, exist at storeroom 2,3,4,5,6 situation that is used for the framework or door storage portion or the shelf 80 etc. that support containing box (storage box body 520) is installed, fixed part, the installing component of shelf 80 etc. of the hold-down screw of framework, door storage portion need to be utilized to the secure components such as screw, fixed part, holding member and fastening or remain to the situation of the inner side (case inner side) of shutter door thereby exist.In this case, exist secure component, fixed part, holding member to the outstanding situation in door inner space, if contact with Vacuumed insulation panel 400, just may damage the outsourcing material of Vacuumed insulation panel, therefore preferably configure or filled polyurethane foam with the thickness that can not damage Vacuumed insulation panel 400 in the inner side of shutter door.But, such as, in the time need to not being installed on especially the installation fitting (secure component, fixed part, holding member etc.) of storeroom inner side (inboard side) of shutter door, also Vacuumed insulation panel 400 can be pasted to inner panel.In addition, when avoiding installation fitting Vacuumed insulation panel being set, also Vacuumed insulation panel can be pasted to inner panel.

In addition, thering is profile parts (outside plate) and inner part (inner panel), be formed at door inner space configuration Vacuumed insulation panel 400 between profile parts and inner part, in the case of filling the hard polyurethane foams as foaming heat insulation part, if make the density of foaming heat insulation part be greater than 60kg/m between profile parts or inner part and Vacuumed insulation panel 400 ³the maintenance intensity or the constant intensity that are screw etc. to the fixed part being fixed for the framework that supports containing box (storage box body 520) are improved, even if therefore receive weight at box body 520, door is also difficult to distortion, the discrepancy of box body 520 can be stably carried out, refrigerator, equipment that reliability is high can be obtained.In addition, the maintenance intensity or the constant intensity that are screw etc. for the fixed part of the miscellaneous part such as fixed handle are improved, therefore when being installed on as door installing components such as the handles of miscellaneous part, door installing component is improved to the installation strength of door, therefore door is difficult to distortion, the switching of door can be stably carried out, refrigerator, equipment that reliability is high can be obtained.In addition, if make to be greater than 60kg/m as the hard polyurethane foams of foaming heat insulation part between profile parts or inner part and Vacuumed insulation panel 400 ³, the Deflection Modulus of Elasticity of foaming heat insulation part is improved, and the intensity of door is also improved.

At this, Vacuumed insulation panel 400 can be disposed at all shutter door or a part of shutter door.For example, such as, when in gas and heat insulating box 700, the temperature difference of (such as, in storeroom) is smaller outside (storeroom of the refrigerated storage temperature band such as refrigerating chamber 2, vegetable compartment 5), even Vacuumed insulation panel 400 is disposed to shutter door, the effect that heat-proof quality is improved is also less.In this case, also can guarantee sufficient heat-proof quality even if Vacuumed insulation panel 400 is not configured to shutter door.Vacuumed insulation panel 400 is when the temperature difference of (such as, in storeroom) is larger in gas and heat insulating box 700 outside the storeroom of cryogenic temperature band (such as ice-making compartment 3, switch room 4, the refrigerating chamber 6 etc.), if Vacuumed insulation panel 400 is disposed to shutter door, the effect that heat-proof quality is improved is larger.Therefore,, in the situation of the storeroom of the cryogenic temperature band that in gas and heat insulating box 700, the temperature difference of (for example, in storeroom) is larger outside, by Vacuumed insulation panel 400 is disposed to shutter door, can guarantee sufficient heat-proof quality.

Above, in the heat insulating box 700 or refrigerator 1 or equipment of present embodiment, with respect to by the space 315 forming between outer container 710 and interior case 750 and the Ji Men inner space, inner space of shutter door spatial volume altogether, the shared volume ratio of Vacuumed insulation panel 400 is the filling rate of Vacuumed insulation panel 400 in predetermined scope (for example more than 40% below 80%).Therefore, can make the wall thickness (for example, distance between outer container 710 and interior the case 750 and thickness of shutter door) of heat insulating box 700 thinner than prior art, therefore heat insulating box 700, refrigerator 1, the equipment of the internal volume excellent in efficiency in energy-conservation and storeroom can be provided.Therefore, even if do not change the appearance and size of heat insulating box 700 or refrigerator 1, also can make interior volume specific ratio in storeroom existing large, therefore can increase compared to existing technology the collecting article that the inside of heat insulating box 700 can be received.Therefore, can provide heat insulating box 700 more energy-conservation than prior art and that heat-proof quality good, commodity value is high, refrigerator 1, hot water supply device, showcase, equipment.

In addition, by increasing the filling rate of the Vacuumed insulation panel 400 in space 315, the filling rate of the hard polyurethane foams in space 315 reduces.In the heat insulating box 700 of present embodiment, make the density ratio prior art of hard polyurethane foams (for example be greater than 60kg/m greatly ³), more than the large 15.0MPa of Deflection Modulus of Elasticity (about 6MPa～10MPa) that the Deflection Modulus of Elasticity that makes hard polyurethane foams is the hard polyurethane foams that uses than existing heat insulating box.Therefore, the heat insulating box 700 of present embodiment can also suppress the strength decreased causing because of the reduction of the filling rate of hard polyurethane foams, do not exist heat insulating box 700 because tolerating the problems such as the crooked distortion causing because of the weight of the collecting article in reserve accommodation space or storeroom or shutter door, can obtain heat insulating box 700, refrigerator 1, equipment that reliability is high.

Therefore, at the refrigerator 1 of present embodiment or possess in the equipment of the heat insulating box 700 with Vacuumed insulation panel 400, heat insulating box 700 can be suppressed crooked and make the situation that the shutter door such as shutter door inclination cannot smooth and easy switching, in addition, the deterioration of the outward appearance causing because of distortion can be suppressed.In addition, can prevent shutter door and for seal heat insulating box peristome sealing gasket contact-making surface (sealing surface) thus position relationship depart from and produce the situation that gap is flowed out air in storeroom (being cold air in the situation of refrigerator) outside heat insulating box.Thus, even if the performance that uses in a large number Vacuumed insulation panel 400 also can suppress heat insulating box 700 reduces, reliability reduces, there is good heat-proof quality, therefore can obtain refrigerator energy-conservation and that reliability is high or there is the heat insulating box of Vacuumed insulation panel or possess Vacuumed insulation panel equipment, possess the equipment of heat insulating box.

At this, when heat insulating box 700 when for refrigerator is the large elongated rectangular shape of the length of height over width direction of above-below direction, compare partition wall 24 between the bottom surface sections 780, top 740, storeroom of approximate horizontal configuration etc., roughly sidewall 790, the back face wall 730 of configuration are elongated shape vertically, therefore easily distortion a little less than rigidity.Therefore,, by as in this embodiment the filling rate of Vacuumed insulation panel 400, coating rate being set in preset range, can improve the intensity (rigidity) of heat insulating box 700.In addition, by being set, protuberance 450 or jut 910 also can improve casing intensity.In addition, be arranged to make one end of protuberance 450 overlapping with predetermined length X with the Vacuumed insulation panel 400 that is disposed at recess 440 or the 2nd recess 441, and the other end is connected to side surface part 790, thereby can make Vacuumed insulation panel 400 be integrally formed via hard polyurethane foams and protuberance 450, in addition, can make Vacuumed insulation panel 400 be integrally formed via hard polyurethane foams and sidewall 790, therefore can improve the intensity of casing 700.

Figure 21 be represent Vacuumed insulation panel 400 with respect to the side surface part 790 of heat insulating box 700 and the shared area ratio (side back side coating rate) of the surface area of back part the figure with the relation of box deformation amount, be result of calculation.About the intensity of heat insulating box, sidewall 790, back face wall 730 be shaped as elongated oblong-shaped, with the roughly square shape phase specific rigidity of top wall 740, underside wall 780, partition wall 24 etc. a little less than, therefore by more than the side back side coating rate of Vacuumed insulation panel 400 is set as to predetermined value, can improve casing intensity.At this, the area ratio (side back side coating rate) shared with respect to the surface area of sidewall 790 and back face wall 730 to Vacuumed insulation panel 400 describes with the relation of casing intensity.

In Figure 21, transverse axis represents that Vacuumed insulation panel 400 is with respect to the sidewall 790 of heat insulating box 700 and the shared area ratio (side back side coating rate) of the surface area of back face wall 730, and the longitudinal axis represents the deflection of casing.At this, the density of establishing polyurethane is 60kg/m ³, Vacuumed insulation panel 400 filling rate be 40%, the box deformation amount of laterodorsal area ratio (side back side coating rate) while being 50% be 1.The Deflection Modulus of Elasticity that calculates the Vacuumed insulation panel 400 using is 20MPa, the measurement result of the Deflection Modulus of Elasticity of the Vacuumed insulation panel using based on reality, is used than the large parts of the Deflection Modulus of Elasticity of existing hard polyurethane foams (about 6MPa～10MPa).At this, in the time changing area ratio (side back side coating rate), the filling rate of Vacuumed insulation panel is fixed as 40%, if therefore the area ratio of Vacuumed insulation panel (side back side coating rate) increases, and the less thick of Vacuumed insulation panel.

In addition, be an example for the refrigerator 1 calculating, suppose that 4 above (for example 4 or 5 or 6 specifications), internal volumes are that 500L level, power consumption are about the refrigerator below 40W.Distance (wall thickness) the average out to 30mm that comprises the plate thickness between outer container 710 and interior case 750, supposes that the thickness of slab of outer container 710, interior case 750 is respectively 1mm, thereby the thickness in space 315 (thickness in wall) is 28mm.The density of hard polyurethane foams is 60kg/m ³, Vacuumed insulation panel 400 thermal conductivity be 0.0021(W/mK), the thermal conductivity of hard polyurethane foams is 0.019(W/mK), Vacuumed insulation panel 400 heat-proof quality compared with hard polyurethane foams got well approximately 10 times of left and right.

In Figure 21, transverse axis represents that Vacuumed insulation panel 400 is with respect to side walls and the shared area ratio (laterodorsal Vacuumed insulation panel coating rate) of back face wall surface area altogether, the box deformation amount (amount of inclining of casing) when the longitudinal axis represents that the heat insulating box 700 to having shutter door has applied predetermined load.At this, the deflection of casing is illustrated in the deflection of the left and right directions of the sidewall upper of heat insulating box while having applied predetermined load apart from the height and position of approximately 1/4 left and right above of the sidewall of a side of for example heat insulating box along general horizontal direction (being left and right directions while laterally, observing front openings portion in front).

Known in Figure 21, the area ratio of Vacuumed insulation panel 400 is larger, and box deformation amount is less.The area ratio (laterodorsal Vacuumed insulation panel coating rate) that makes side/back side is 70% when above, and the rate of change of box deformation amount diminishes.That is, till the area ratio at side/back side is 70% left and right, large if area ratio becomes, box deformation amount sharply diminishes, but becomes 70% when above when the area ratio at side/back side, even if area ratio change greatly, box deformation amount changes hardly.Therefore, the area ratio at side/back side (laterodorsal Vacuumed insulation panel coating rate) is 70% when above, and the reduction ratio of the deflection of casing is minimum, even if the side backside area ratio of Vacuumed insulation panel increases, box deformation amount also changes hardly.This be considered to due to, the laterodorsal area ratio of Vacuumed insulation panel approaches saturated for the influence degree of casing intensity substantially.

At this, make the filling rate of Vacuumed insulation panel be fixed as 40% and calculate, if therefore increase the configuration area of Vacuumed insulation panel 400, the thickness attenuation of Vacuumed insulation panel 400.Till the area ratio at the side/back side of Vacuumed insulation panel is 70% left and right, if increase the area ratio at side/back side, compared with the recruitment of the box deformation causing with the thickness attenuation of Vacuumed insulation panel, the reduction that the intensity that becomes the casing causing greatly because of the configuration area of Vacuumed insulation panel improves the box deformation causing is larger, and therefore the rigidity of casing improves, the deflection of casing reduces.But, when the area ratio at the side/back side of Vacuumed insulation panel exceedes approximately 70%, the reduction that the recruitment of the box deformation that the strength decreased of the casing causing because of the thickness attenuation of Vacuumed insulation panel causes and the intensity that becomes the casing causing greatly because of the configuration area of Vacuumed insulation panel improve the box deformation causing is same degree, and the minimizing degree of the deflection of casing diminishes.

In addition, while making the thickness attenuation of Vacuumed insulation panel by increasing the configuration area ratio (coating rate) of Vacuumed insulation panel, the thickness thickening of polyurethane foam.Till configuration area ratio is 70% left and right, the thickness of Vacuumed insulation panel is more than predetermined thickness, therefore compare the reduction of the thickness of Vacuumed insulation panel, the impact of the intensity of the recruitment of area ratio on heat insulating box is larger, box deformation amount reduces, if but further increase the configuration area ratio of Vacuumed insulation panel, the less thick of Vacuumed insulation panel, it is large that the thickness of polyurethane becomes, thereby the impact of the intensity of the recruitment of the configuration area ratio of the recruitment of the thickness of polyurethane and Vacuumed insulation panel on heat insulating box becomes equal, the minimizing degree of box deformation amount diminishes.

Therefore,, if more than the area ratio at the side/back side of Vacuumed insulation panel 400 (side back side coating rate) is set as to predetermined value (70%), just can obtain casing intensity, therefore can obtain the casing that reliability is high.In addition, if more than the area ratio at the side/back side of Vacuumed insulation panel is set as to predetermined value (70%), become the region that box deformation amount changes hardly, even if therefore the configuration area of Vacuumed insulation panel produces uneven, the deflection of casing also changes hardly, therefore can obtain high strength, aesthetic appearance is good, reliability is high heat insulating box, refrigerator, showcase, equipment.If make the coating rate of Vacuumed insulation panel 400 be predetermined value above (more than 60%) and the area ratio at the side/back side of Vacuumed insulation panel 400 is set as to the 2nd predetermined value (70%) more than, heat-proof quality improves, and can reduce box deformation amount, therefore can obtain heat-proof quality is large, reliability is high and energy-conservation refrigerator, showcase, equipment.

At this, fix and expand the configuration area of Vacuumed insulation panel 400 if make the thickness of Vacuumed insulation panel, the coating rate of Vacuumed insulation panel, filling rate all can increase, if but the filling rate of Vacuumed insulation panel 400 increases, cost increases, therefore do not change filling rate and when increasing coating rate and improve the intensity of heat insulating box 700 cost lower, and can increase the configuration area of Vacuumed insulation panel, therefore heat-insulating efficiency improves.Therefore, be more than 70% by making the filling rate of Vacuumed insulation panel 400 be more than 40%, making the area ratio (laterodorsal Vacuumed insulation panel coating rate) at side/back side, can with low-cost high-efficiency guarantee the intensity of heat insulating box.Therefore, for example, if more than the area ratio at the side/back side of Vacuumed insulation panel (laterodorsal Vacuumed insulation panel coating rate) is set as to the 2nd predetermined value (be the area ratio that diminishes of the reduction ratio of the deflection of heat insulating box, be 70% left and right), wall thickness (thickness of attenuate polyurethane) that just can attenuate heat insulating box 700, increase the internal volume of storeroom.The configuration area (laterodorsal Vacuumed insulation panel coating rate) of the Vacuumed insulation panel 400 of sidewall 790 and back face wall 730 is larger, the deflection of heat insulating box 700 is less, therefore can increase the intensity of heat insulating box 700, heat insulating box 700, refrigerator 1 that high strength and heat-proof quality are good can be provided, possess the equipment of heat insulating box.

(polyurethane physical property)

At this, physical property, the characteristic of the hard polyurethane foams that is filled in heat insulating box 700 are described.Hard polyurethane foams, by increasing free foaming density, can provide the intensity stabilization after foaming, the heat insulating box 700 that outward appearance is good, quality is high.

At this, free foaming density refers to, not in the airtight space such as casing, makes polyurethane foam but the density of hard polyurethane foams while making polyurethane foam under open mode in the container opened etc.And in fact, due to foaming in the airtight narrow space of polyurethane in heat insulating box 700, expansion, the density of therefore foaming in the airtight narrow space such as heat insulating box 700, the polyurethane that expands is larger than the free foaming density of foaming under the state of opening, the polyurethane that expands.

The density of the hard polyurethane foams after foaming by raising, as illustrated in Figure 16, can increase Deflection Modulus of Elasticity, but in the time making polyurethane stock solution flow directly into heat insulating box 700 to fill to increase density, for the little polyurethane of the expansion ratio of present use, free foaming density is little of 26～28kg/m ³expansion ratio is little, if therefore the stream thickness of the mobile part of polyurethane exists size not, and foaming degree inequality, near inlet 703,704 and terminal part (away from the position of inlet) polyurethane density easily produce inequality, be difficult to obtain stable intensity.

In the present embodiment, for example, by using the existing (about 25～28kg/m of free foaming density ratio ³) (for example free foaming density is about 30～45kg/m for large hard polyurethane foams ³), even exist a little size not at the stream thickness of the mobile part of polyurethane, also can stably foam because expansion ratio is large, can reduce the inequality of the density after foaming.Therefore, be easy to make the density of the polyurethane after foaming roughly even.

The foaming body that hard polyurethane foams is such, has bubble in inside, and density is less, and bubble is more, and heat insulation effect is higher.Therefore, in prior art, heat insulating box 700 makes density after the foaming of the hard polyurethane foams being used for about 25～28kg/m ³the hard polyurethane foams of little density.Want to use this existing polyurethane foam make Deflection Modulus of Elasticity for 15MPa above when guaranteeing the intensity of heat insulating box 700, for example, the in the situation that in wall, thickness being 28mm, in the heat insulating box that is 8mm at the thickness of removing the polyurethane after the thickness of Vacuumed insulation panel, must inject, the lucky loading of packing ratio polyurethane (is to the polyurethane amount becoming when can not applying irrational load etc. and just fill hard polyurethane foams in the casing of object, it is even that density after foaming easily becomes) many polyurethane, density easily produces inequality.

And then, due to the polyurethane that must inject, the lucky loading of packing ratio is many, therefore need in the time that polyurethane injects, pressurize or extend the filling time, thereby polyurethane is from the junction surface of the profile of heat insulating box 700, shutter door etc., gap (junction surface of for example outer container 710 and interior case 750) spills, cannot inject the polyurethane of (cannot fill) required scheduled volume, the density that is difficult to guarantee to be filled into the hard polyurethane foams after casing is for for example, than predetermined value (60kg/mm ³) large density.In addition, if polyurethane spills from the profile of casing, just need to remove the operation of the polyurethane spilling, activity duration or built-up time need to increase, and cause cost rising, aesthetic appearance to reduce.Therefore the density that, is filled into the polyurethane after heat insulating box in prior art is less than 60kg/m ³, be about 25～30kg/m ³, up to about 55kg/m ³below.

At this, in the present embodiment, the amount of having studied by reducing the expanded material that comprises in polyurethane stock solution etc. increases free foaming density.Be for example that the polyurethane stream thickness that 8mm(removes after the thickness of Vacuumed insulation panel is about 8mm at the thickness of polyurethane) heat insulating box 700 in, by free foaming density is set as to predetermined value (30kg/m ³preferred 35kg/m above, ³above), can make density under the lucky loading density of the polyurethane after casing (do not apply the ground such as irrational load be filled into) compare 60kg/m ³greatly, it is more than 15MPa can making the Deflection Modulus of Elasticity of hard polyurethane foams.Therefore, the problem of the heat insulating box that density unevenness, the polyurethane that can eliminate polyurethane spills and so on, can obtain high, the high-intensity heat insulating box 700 of reliability, refrigerator 1, showcase, possess the equipment of heat insulating box.

At this, worry because making the free foaming density ratio predetermined value of hard polyaminoester large, the impact of polyurethane density after increase foaming on heat-proof quality, but as illustrated in Figure 17～Figure 21, for example the thickness of the polyurethane at the configuration position of Vacuumed insulation panel 400 is set as to predetermined value following (below 11mm, or 6mm is following), or thickness in the thickness/wall of polyurethane is set as below predetermined value (0.3), or when the filling rate of Vacuumed insulation panel 400 is set as to preset range (more than 40% below 90%), can reduce the impact of the heat-proof quality on heat insulating box (to heat insulating box 700, the impact of the heat-proof quality of the heat insulating box of shutter door).In addition, the thickness that makes polyurethane is 11mm when following, is predetermined value (for example 35kg/m by making free foaming density ³) more than, can set the lucky loading (can adjust lucky loading) that does not cause polyurethane and spill for.

The heat insulating box 700 of present embodiment can make the wall ratio of heat insulating box 700 existing thin, in addition, guarantee predetermined intensity, in the time of filling polyurethane, polyurethane is also difficult to spill from profile, can meet required quality, heat insulating box 700 energy-conservation, internal volume excellent in efficiency can be provided.; the appearance and size that does not change heat insulating box 700 or refrigerator 1 or possess the equipment of heat insulating box just can make the reserve storage volume (for example, being case internal volume or storeroom volume in the situation of refrigerator) of heat insulating box larger than existing, can increase compared to existing technology the collecting article that the inside of heat insulating box 700 can be stored.Therefore, can obtain that user is easy to use, thermal insulation good, high strength and high heat insulating box 700 or the refrigerator 1 of reliability or possess the equipment of heat insulating box.In addition,, when the storage volume settings of indoor (in storeroom) is become to equal with prior art, can make appearance and size correspondingly reduce the amount that wall thickness can reduce.

At this, refrigerator 1 possesses the cooling device for the cooling air (cold air) of supplying with to multiple storerooms such as refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5.This cooling device such as,, by formations such as compressor 12, refrigerant piping (condensation pipe arrangement 725), decompressor (expansion valve, capillary etc.), coolers 13, forms freeze cycle.Forming compressor 12, decompressor in the inscape of this freeze cycle is located in the Machine Room 1A forming in the back underside (can be also back side upside) of heat insulating box 700 that forms refrigerator 1.Condensation pipe arrangement 725 is located at for example sidewall 790 or back face wall 730 or the top wall 740 of heat insulating box 700.Form the fan grill of reserve accommodation space etc. by the back side at storeroom, the storeroom side of wall 730 is provided with and the back side cover of the parts of interior case 750 splits overleaf, and cooler 13 is located in the cooler chamber 131 forming between the back side cap assemblies such as interior case 750 and fan grill.In addition, in this cooler chamber 131, be also provided with for will be by the chilled air of cooler 13 (cold air) air-supply the fan 14 for circulating cold air to each storerooms such as refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5.In addition, be provided with control substrate chamber 31 on the top (or substantial middle height and position of back face wall 730) of top wall 740 or the back face wall 730 of heat insulating box 700, be provided with control device 30 controlling in substrate chamber 31, this control device 30 is controlled running action control or the temperature inside the box control etc. of the rotating speed of compressor 12 or circulating cold air fan 14 etc.

At the refrigerator 1 forming like this, the gas refrigerant of the HTHP of being sent by the compressor 12 being disposed in the 1A of Machine Room, for example, at refrigerant piping (condensation pipe arrangement) 725 by being condensed, become the liquid refrigerant of cryogenic high pressure, the liquid refrigerant of cryogenic high pressure is reduced pressure into the gas-liquid two-phase cold-producing medium of low-temp low-pressure by decompressor, while arriving cooler 13, become for example-20 DEG C of following low temperature.Air in the gas-liquid two-phase refrigerant cools cooler chamber 131 of this low-temp low-pressure, and use fan 14 to be supplied to each storerooms such as refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5 by circulating cold air this cooled air, thereby the storerooms (or collecting article of receiving in these storerooms) such as refrigerated compartment 2, refrigerating chamber 6, vegetable compartment 5.On the other hand, the gas-liquid two-phase cold-producing medium of the low-temp low-pressure of cooling air in cooler chamber 131, is evaporated by the air heat in cooler chamber 131, becomes the gas shape cold-producing medium of low pressure and is inhaled into once again compressor 12 compressed.

As mentioned above, in the refrigerator 1 of present embodiment, making filling rate that Vacuumed insulation panel 400 is Vacuumed insulation panel with respect to the shared ratio of total volume of internal capacity of the door inner space of the space 315 forming between outer container 710 and interior case 750 and shutter door is predetermined value (for example 40%～80%).Therefore, for example,, even thickness (distance (thickness) between outer container 710 and interior the case 750 or thickness of shutter door) is thinner than prior art in the wall of heat insulating box 700, also can guarantee heat-proof quality.Therefore, in the refrigerator 1 of present embodiment, the heat-proof quality of heat insulating box 700 is improved, thereby cold air, collecting article in multiple storeroom 2,3,4,5,6 are not easy to warm, and therefore can shorten for duration of runs of cooling compressor 12 or reduce the air quantity of fan.Therefore, can the air quantity of the cooling required air (cold air) in storeroom 2,3,4,5,6 be suppressed littlely, can reduce the rotating speed of compressor 12 or extend the running OFF time, therefore can carry out energy-conservation running.Therefore, in the refrigerator 1 of present embodiment, can be more energy-conservation than existing.In addition, refrigerator 1 does not change appearance and size just can expand storeroom volume (case internal volume) compared to existing technology, can increase compared to existing technology the collecting article that can store in storeroom, therefore can obtain refrigerator easy to use, equipment.

In addition, if will be disposed at the substantial middle position of above-below direction with the refrigerating chamber 6 of the temperature difference maximum of outer gas, can suppress from above and the heat that is derived from outer gas that enters towards refrigerating chamber 6, the hot entering surface that therefore can make heat enter refrigerating chamber 6 from outer gas cut is 4 (shutter door above, left surface, right flank, these 4 faces of the back side).Therefore, can obtain energy-conservation refrigerator 1.

In addition, according to present embodiment, the Deflection Modulus of Elasticity that makes the hard polyurethane foams that is filled in 315Ji Men inner space, space is more than 15.0MPa, therefore the casing intensity of heat insulating box 700 can meet predetermined intensity, thereby can suppress crooked distortion that heat insulating box 700 causes because tolerating the weight of collecting article.Therefore, heat insulating box 700 can be suppressed crooked and shutter door is above tilted, the deterioration of outward appearance can be prevented.In addition, thereby staggering and produce the situation that gap makes the air (cold air) in refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5, ice-making compartment 3, switch room 4 spill to the outside of heat insulating box 700, refrigerator 1 in the position that can suppress the seal member to sealing between the front openings portion of shutter door and heat insulating box, thereby can obtain more energy-conservation refrigerator, equipment.

In addition, the distribution of the filling rate of the Vacuumed insulation panel 400 in inner space about space 315 or door, also can be according to the temperature difference of outer gas and each storeroom, and in space 315 or door inner space, change the filling rate of Vacuumed insulation panel 400 according to preposition.

For example, as the refrigerating chamber 6(of low temperature chamber or ice-making compartment 3, switch room 4), the temperature difference maximum of the temperature in its storeroom and outer gas.Therefore, can make in the left surface of the heat insulating box 700 of refrigerating chamber 6 scope in opposite directions, right flank, the back side and above the Vacuumed insulation panel 400 of (shutter door) filling rate than with the wall of other storerooms refrigerating chamber 2, the vegetable compartment 5 of hot room (for example as) scope in opposite directions (for example left surface, right flank, the back side and above (shutter door)) large (for example, more than 60%).By such formation, can suppress to the minimum low temperature chamber of temperature is the heat intrusion of refrigerating chamber 6, can obtain more energy-conservation refrigerator 1, equipment.

For example, outer temperature degree, for for example 30 DEG C time, becomes in the 1A of Machine Room for example more than 40 DEG C.The temperature of controlling substrate chamber 31 also rises to for example more than 40 DEG C., Machine Room 1A and control wall, the partition wall 24 between substrate chamber 31 and the storeroom of position in opposite directions, compares wall, the partition wall 24 of other parts, larger with the temperature difference in storeroom.Therefore, thermal capacitance is easily invaded near the storeroom of configuration Machine Room 1A, control substrate chamber 31.Therefore,, being disposed at Machine Room 1A or controlling wall, the partition wall 24 between substrate chamber 31 and storeroom, can make the filling rate of Vacuumed insulation panel 400 improve greatly heat-proof quality than other walls, partition wall 24.For example be disposed at Machine Room 1A or controlling wall, the partition wall 24 between substrate chamber 31 and storeroom, the filling rate that can make Vacuumed insulation panel 400 is more than 60% (it is more than 70% making the side back side coating rate of Vacuumed insulation panel 400), is more than 40% (below 90%) and make the filling rate of the Vacuumed insulation panel 400 of other walls, partition wall 24.By such formation, can suppress heat and invade near storeroom from the high Machine Room 1A of temperature, control substrate chamber, can make refrigerator 1 energy-saving more.

The heat insulating box 700 of present embodiment for example can and possess storage for the heater of heating water and stay the water storage device by the tank of the warmed-up water of this heater.By the internal configurations tank at heat insulating box 700, can be than existing little heat insulating box 700, tank is heat insulation by appearance and size, can make water storage device save space.In addition, present embodiment such as, just can be applied as long as the equipment (refrigerator, showcase, refrigerator, hot-water supply, hot shot water machine, aircondition etc.) with the thermal wall with Vacuumed insulation panel.

In embodiment of the present utility model, concavo-convex etc. without arranging at Vacuumed insulation panel 400, also be the shape along the concaveconvex shape of outsourcing material without the core that makes to enclose in outsourcing material, therefore Vacuumed insulation panel 400 can use flat object, so, core has the shot-like particle of mobility without use, can use the inorfils such as glass fibre, the fiber-like cores such as organic fiber, and need to concavo-convex etc. complicated processing be set at outsourcing material, thereby can obtain low cost, treatability is good, the heat insulating box that heat-proof quality is high, refrigerator, equipment.

At this, in the present embodiment, the 3rd sandwiched parts can be identical with the 1st sandwiched parts.In addition, the 2nd sandwiched parts also can be identical with the 1st sandwiched parts.

(effect that embodiment plays)

As mentioned above, in the present embodiment, forming, at least have sidewall 790, back face wall 730 by outer container 710 and interior case 750, have above in the heat insulating box 700 of peristome, possess: protuberance 450, be formed at the corner part of back face wall 730 and sidewall 790, with respect to back face wall 730 to peristome is side-prominent above, recess 440(can be also the 2nd recess 441), form at the interior case 750 that forms back face wall 730, cave in rearward for protuberance 450 from front face side read fortune, with flat Vacuumed insulation panel 400, at least arrange forming between the interior case 750 of back face wall 730 and outer container 710, be disposed between the interior case 750 and outer container 710 of recess 440 position in opposite directions, at least upper large than the width of recess 440 (representing with the scope W of recess 440 in Fig. 8) at width (or length direction), protuberance 450 is formed as with Vacuumed insulation panel 400 overlapping with predetermined length X, between Vacuumed insulation panel 400 and the interior case 750 of formation recess 440, and Vacuumed insulation panel 400 and forming while filling bonding agent as sandwiched parts between the interior case 750 of protuberance 450, even if the thickness of the bonding agent between Vacuumed insulation panel 400 and interior case 750 is less, due to protuberance 450 and Vacuumed insulation panel 400 overlap length X, therefore corresponding to the amount of overlapping length X, the bonding thickness of the bonding agent hard polyurethane foams of foaming heat insulation part (for example as) increases, Vacuumed insulation panel 400 can via the bonding agent in protuberance 450 with form interior case 750(or the outer container 710 of recess 440) bonding securely.In addition, the interior case 750 of the interior case 750 of formation recess 440 and formation sidewall 790 also can be bonding securely via protuberance 450.Therefore, even the thickness of the bonding agent between Vacuumed insulation panel 400 and the interior case 750 at attenuate recess 440 places, also can recess 440, Vacuumed insulation panel 400, sidewall 790 be integrally formed via the large protuberance 450 of bonding agent thickness, therefore can configure the wall thickness of the recess 440 of Vacuumed insulation panel by attenuate, and can improve the intensity of casing or wall.

At this, if be used as the hard polyurethane foams of the foaming heat insulation part with self bonding as the bonding agent of sandwiched parts, even if the thickness of the hard polyurethane foams between Vacuumed insulation panel 400 and interior case 750 is set for and is thinned to below predetermined 11mm, also due to protuberance 450 and Vacuumed insulation panel 400 overlap length X, corresponding to the amount of overlapping length X, can make the thickness of the hard polyurethane foams between Vacuumed insulation panel 400 and interior case 750 increase, Vacuumed insulation panel 400 can be via the hard polyurethane foams in protuberance 450 and interior case 750(or outer container 710) bonding securely.In addition, even the thickness of the hard polyurethane foams between Vacuumed insulation panel 400 and the interior case 750 of attenuate and recess 440 position in opposite directions, also can be integrally formed via the hard polyurethane foams in protuberance 450 and sidewall 790 with the Vacuumed insulation panel 400 of recess 440 position in opposite directions, even if therefore attenuate forms the wall thickness of the part of recess 440, also can improve the intensity of casing intensity or wall.

In addition, formed by outer container 710 and interior case 750, the surrounding of wall 730 has at least one surrounding wall (for example sidewall 790 overleaf, roof 740, underside wall 780, partition wall 24), have above in the heat insulating box 700 of peristome, back face wall 730 has at the protuberance 450 forming with the corner part of surrounding wall, with the recess 440(caving in rearward for protuberance 450 from front face side read fortune or the 2nd recess 441), and possess be disposed at and recess 440(or the 2nd recess 441) between the interior case 750 of position in opposite directions and outer container 710 and at least on width or length direction than the scope W of the width P(recess of recess) large flat Vacuumed insulation panel 400, protuberance 450 is formed as and the overlapping predetermined length X of Vacuumed insulation panel 400, and the interior case 750 and Vacuumed insulation panel 400 of recess 440 position in opposite directions between, and and the interior case 750 and Vacuumed insulation panel 400 of protuberance 450 position in opposite directions between, if fill bonding agent as sandwiched parts, even the less thick of the bonding agent between Vacuumed insulation panel 400 and interior case 750, also due to protuberance 450 and Vacuumed insulation panel 400 overlap length X, corresponding to the amount of overlapping length X, can make the bonding thickness of the bonding agent hard polyurethane foams of foaming heat insulation part (for example as) increase, Vacuumed insulation panel 400 can via the bonding agent in protuberance 450 with form interior case 750(or the outer container 710 of recess 440) bonding securely.In addition, interior case 750 and at least one surrounding wall (for example sidewall 790, roof 740, underside wall 780, partition wall 24) of formation recess 440 also can be bonding securely via protuberance 450.Therefore, even the thickness of the bonding agent between Vacuumed insulation panel 400 and the interior case 750 at attenuate recess 440 places, also can recess 440, Vacuumed insulation panel 400, at least one surrounding wall (for example sidewall 790, roof 740, underside wall 780, partition wall 24) be integrally formed via the large protuberance of sandwiched component thickness (bonding agent thickness), therefore can configure the wall thickness of the recess 440 of Vacuumed insulation panel by attenuate, and can improve the intensity of casing or wall.

In addition, surrounding wall for example, for being connected the sidewall 790 that forms chamber (storeroom) with back face wall 730, roof 740, underside wall 780, when any of partition wall 24, even if the sandwiched parts between Vacuumed insulation panel 400 and the interior case 750 at attenuate recess 440 places are the thickness of bonding agent, the Vacuumed insulation panel 400 that is disposed at recess 440 also can for example, via the sandwiched parts (bonding agent) of protuberance and at least one surrounding wall (sidewall 790, roof 740, underside wall 780, partition wall 24) be integrally formed, even if therefore attenuate forms the wall thickness of the part of recess, also can improve the intensity of casing or wall.In addition,, if use hard polyurethane foams as sandwiched parts (bonding agent), can also improve predetermined heat-proof quality.

In addition, as sandwiched parts (bonding agent), fill front for thering is the liquid of mobility or two-phase state, filling the foaming heat insulation part with self bonding of post-foaming as bonding agent performance function if use, even the gap smaller between Vacuumed insulation panel 400 and the interior case 750 at recess 440 places, also can flow into narrow gap with liquid condition or two-phase state, therefore sandwiched parts (bonding agent) can be filled equably, adhesive strength or constant intensity can be guaranteed.Even if therefore attenuate wall thickness also can be guaranteed the intensity of casing.In addition, also, as thermal insulation barriers performance function, therefore heat-proof quality also improves.

In addition, in the situation that using bonding agent as sandwiched parts, in the time that bonding agent is the hard polyurethane foams as foaming heat insulation part, such as, in the part (recess 440 grades dispose the wall of Vacuumed insulation panel 400) of the thinner thickness of polyurethane, effect as thermal insulation barriers reduces, but as long as is used as in the present embodiment the hard polyurethane foams of sandwiched parts as bonding agent.In addition, the thicker part (for example not configuring the wall of Vacuumed insulation panel 400 etc.) of thickness that can guarantee polyurethane can obtain the effect as thermal insulation barriers, therefore can be used as thermal insulation barriers uses, therefore intensity and the heat-proof quality of casing can be guaranteed simultaneously, heat insulating box that high-performance and reliability are high, refrigerator, equipment etc. can be obtained.In addition, hard polyurethane foams has this speciality of the unexistent self bonding of other thermal insulation barriers material, even if therefore do not use other bonding agents, also can directly foam and form the thermal insulation layer that bonds to securely object by the surface at object (interior case 750, Vacuumed insulation panel 400, outer container 710), can obtain cementability and thermal insulation simultaneously.

In addition, even if the thickness that is filled in the bonding agent as sandwiched parts between Vacuumed insulation panel 400 and interior case 750 is less than the thickness of Vacuumed insulation panel 400, also can guarantee wall intensity or casing intensity by Vacuumed insulation panel 400, therefore can attenuate possess the wall thickness of the wall of Vacuumed insulation panel 400.

In addition, if using and the interior case 750 of recess 440 position in opposite directions and Vacuumed insulation panel 400 between the thickness of the bonding agent as sandwiched parts (for example hard polyurethane foams) of filling be set as below 11mm, the less thick of hard polyurethane foams can increase the Deflection Modulus of Elasticity of hard polyurethane foams, even if therefore also can improve intensity.Therefore, also can improve casing intensity even if reduce wall thickness.

In addition, by back face wall 730, sidewall 790, upper wall 24(or roof 740) and lower wall 24(or underside wall 780) form and the heat insulating box of front openings in, possess: Vacuumed insulation panel 400, is forming between the interior case 750 of inner face of back face wall 730 and the outer container 710 of the outside of formation back face wall 730 or forming setting between the interior case 750 of inner face of sidewall 790 and the outer container 710 of the outside of formation sidewall 790; With sandwiched parts, between Vacuumed insulation panel 400 and interior case 750, fill or enclose or coating or setting, by Vacuumed insulation panel 400 with interior case 750 is bonding or cementation or fixing, sandwiched parts are polyurethane foam, the thickness of sandwiched parts is below 11mm, therefore can increase the Deflection Modulus of Elasticity of polyurethane foam, thereby even if the thickness of polyurethane foam reduces also can improve intensity.Therefore, also can improve casing intensity even if reduce wall thickness.
