Description

200300343 发明. Description of the invention: [Yun ^ Ming ^ ^ ^ pull ^ cold shell super ^ field of the invention The present invention relates to a refrigerator using a vacuum insulation material. I: Prior technology:! BACKGROUND OF THE INVENTION In recent years, reviews of energy-saving or space-saving targets for refrigerators have been started, and vacuum insulation materials with high absolute performance have been used to improve the thermal insulation of refrigerators. 14b. The vacuum insulation material and the rigid polyurethane foam material of the resin foam have thermal insulation properties of several times to 10 times. With the continuous improvement of energy-saving requirements, it is imperative to improve the thermal insulation performance by maximizing the use of such vacuum insulation materials within an appropriate range. on the other hand. When the vacuum 2 heating material and the rigid polyurethane foam material are used as a double layer and used in the 钿 ba thermal box of Moringa, the rigid polyurethane foam material and the vacuum thermal material The shrinkage is different, and the appearance of the absolute box is deformed. The Japanese Unexamined Patent Publication No. 6M4Μ690 discloses a method for solving such a problem. Hereinafter, the conventional refrigerator will be described with reference to the drawings. Fig. 40 is a sectional view of a door hinge disposed at an opening portion of a front face of a conventional refrigerator. M Figure 41 is an enlarged view of part a of Figure 40. In the figure, the refrigerator has a metal outer panel, a door frame made of synthetic resin 2, an inner box made of synthetic resin 3, a foamed heat insulation material 4, and a two-percent heat material 5. The release paper 6 interposed between the vacuum insulation material 5 and the outer plate 丨 is larger than the vacuum insulation material 5, so that the vacuum insulation material 5 is positioned on the inner surface of the slab 1 through the release paper 6. In such a structure, although the thermal insulation material 4 is contracted after the foamed thermal insulation material 4 is foamed, a gap X is generated between the outer plate and the release film 300300343 paper 6 due to the action of the release paper 6 To prevent deformation of the outer plate 1. However, in such a refrigerator, it is possible to prevent a person from deforming the appearance of the outer panel, and a gap may be generated between the outer panel and the foamed heat insulating material. Therefore, when the user touches it with his / her hand, the touch feeling is not good due to the depression of the outer plate or the like. 5 Japanese Unexamined Patent Publication No. 6-15 9 922 also discloses a refrigerator equipped with a vacuum insulation material. Fig. 42 is a side sectional view of such a conventional refrigerator. The refrigerator body 7 is composed of an outer box 1A and an inner box 3. The lineable bag-shaped paper material 8 covers the entire space formed by the outer box 1A and the inner box 3, and the paper material 8 is filled with a filling material 4A made of an inorganic porous material. A vacuum heat insulating material 5 is arranged along the shape of the inner and outer boxes 1A and 3 surrounding the space 10. The vacuum insulation material 5 used has metal foil on both sides and has a flat shape. With this structure, the vacuum heat insulating material 5 can be easily stored in the inner and outer boxes 1A and 3, and the gap between the inner and outer boxes 1A and 3 and the vacuum heat insulating material 5 can be operated without blocking. In addition, since a rigid polyurethane 15 gallate foaming material is not required to use a resin foam, and only the vacuum heat insulating material 5 can be used to form a heat insulating box, a very high heat insulating performance can be secured. However, in such a refrigerator, since only the vacuum insulation material 5 which is inferior to the rigid polyurethane foam material is used, the strength is very weak although the heat insulation performance is high. That is, it is easily deformed in appearance. In addition, since the shape of the inner box or the outer box is non-planar, the heat pipes and the like have uneven surfaces. It is difficult to use a plate-shaped vacuum insulation material in a non-planar portion. In addition, in order to improve the heat insulation performance, although it is effective to use a vacuum heat insulating material using an aluminum vapor-deposited film on one plane, it is difficult to use a vacuum heat insulating material using an aluminum vapor-deposited film in terms of reliability. 200300343 [Summary of the invention] Summary of the invention An ice box in which a resin foam and a vacuum insulation material are installed between an outer box and an inner box, and has one of the following structures. 5 (1) The average roughness (Ra) of the centerline of the outer surface of the outer box of the vacuum insulation material disposed on the surface of the outer box is 0.1 μm or more, or the gloss of the outer surface of the outer box is 80 or less.

In addition, those who form the same structure will be described with the same symbols, and detailed descriptions will be omitted. (Embodiment 1) 11 200300343 Embodiment 1 of the present invention will be described with reference to Figs. 1 to 6. The refrigerator is a rigid polyamine-based space-filled resin foam composed of a synthetic resin, such as acrylonitrile, butadiene, and styrene-acrylic acid copolymer (ABS), and an inner box 11 and an iron plate. The formate foam material (polyurethane foam material at a temperature of 5 or less) 13 is formed. The refrigerating compartment 15 and the vegetable compartment 16 are connected to the upper part of the thermal insulation partition wall 14, and the switching compartment π, the ice-making compartment 18, and the freezing compartment 19 are formed in the lower part. A compressor 21 is arranged inside the machine room 20 disposed below the rear portion of the refrigerator 10. The refrigerator 10 includes a refrigerator cooler 22, a refrigerator blower 23, a refrigerator cooler 24, and a refrigerator blower 25. The condenser 26 is arranged at the bottom of the refrigerator 10. The front opening of the refrigerator 10 is provided with a hinge-type refrigerator compartment door (hereinafter, a door hinge) 27 that pivots at one end as a fulcrum, a drawer-type vegetable room door (hereinafter, a door hinge) 28, and a switch room door hinge (below, Door lintel) 29, Door lintel (hereinafter, door lintel) 30 for ice-making rooms, Door lintel (hereinafter, lintel) 31 for freezing rooms. The vacuum insulation material 32, 33, 34, 35, 36, 37, 38, 39, 40, and 41 together with the polyurethane foam material 13 constitute the refrigerator body 10. The vacuum insulation materials 32, 33, 34, and 36 are respectively attached to the top surface, the back surface, the side surface, and the inner side of the machine room constituting surface of the outer box 11. The vacuum insulation material 35 is attached to the bottom surface of the inner box 12. The vacuum heat insulating material 37 is arranged in the heat insulating partition 2014. A vacuum heat insulating material 38 is provided so that an inner box is connected to the inside of the door lintel 27. * Each vacuum insulation material 39, 40, 41 inside the lintels 28, 29, 31 is arranged at the outer iron plate and the middle of the inner box of each lintel. Although not shown in the figure, a vacuum heat insulating material is similarly arranged on the iron plate on the outside of the lintel 30 and the middle portion of the inner box. In addition, the polyamine 12 200300343 surrounded by the freezing chamber 19 and the conversion chamber 17 in the freezing area and the vacuum insulation material 33, 34, 35, and 36 are stepped into a heat insulation box. In addition to the door lintel, the thickness of the heat-insulating wall of the heat-insulating box is preferably 25 to 50 mm. On the other hand, around the refrigerating compartment 15 in the refrigerating field, the polyurethane saki outsourcing material 13 and the vacuum insulation materials 32, 33, and 34 of the vegetable compartment 16 also form an insulation box. The 浐 thermal insulation wall thickness of the heat box body except for the door 扉, including the thickness of the wall thickness of the opening part is = ~ 40 mm. Since a vacuum insulation material having a thickness of 10 to 15 mm is provided in the thermal insulation wall thickness, it can be ensured that the thickness of the polyurethane foam material 13 is ίο 15 20 and a minimum of 10 mm. Therefore, it does not hinder the fluidity of the polyurethane foam material 13 during foaming, and does not cause a decrease in thermal insulation due to rough foam or poor filling. In this way, ensuring the thickness of the vacuum insulation material, while fully exerting the heat insulation property, while maintaining the heat insulation property of the polyurethane foam material 13, can effectively improve the heat insulation performance of the riding wall. In particular, the temperature is steeper inside and outside the library; the temperature in the east and the east is even more fruitful. And will surround the cold bed, the field of cold shirts 19. The insulation wall thickness of the conversion chamber 17 is made not more than

y Therefore, ‘a vacuum insulation material is applied, and the internal volume of the cold bed chamber and conversion chamber η, which has a relatively small volume ratio, can increase the use value of J: Ego vacuum insulation material without affecting the appearance layout. In addition, the insulation wall thickness of the refrigerating room is reduced to 16 to make the refrigerating collar less than the temperature gradient of the inside and outside of the refrigerator, which is relatively small. It is stubborn and shaped because of the application of vacuum insulation materials. The internal volume inside and outside the box _ upward effect of the equalizing water pipe == shown in the figure: a part or a concave-convex shape or a pipe, row, other structure. A large number of vacuum insulation materials are installed. 13 200300343 When the material coverage is increased to the limit, it becomes a special vacuum insulation material that needs to be applied to that part. Or the workability of the vacuum insulation material becomes very poor. Therefore, even if a vacuum heat insulating material is provided that exceeds approximately 80% of the surface area of the outer box, the above-mentioned use efficiency is poor, and the utilization price becomes saturated. That is, in the face of the input of the vacuum insulation material, the upward effect of significantly reducing the thermal insulation performance is significantly reduced. Therefore, it is the same as this embodiment. The vacuum insulation material covers less than 80% of the surface area of the outer box, and the effect is not saturated due to the large amount of vacuum insulation material used. That is, under the condition of high utilization value, the heat absorption load of the system can be effectively suppressed, and the energy saving effect can be improved. In addition, the thermal insulation thickness of the peripheral part of each surface or the part of the partition wall between the cooling chambers is heavy®. In addition, the peripheral edge of the opening will reduce the filling and adhesion of the polyurethane foamed material 13 and decrease the heat insulation property. If you avoid such additional vacuum insulation ... material ..., the rate of coating ', even the coverage rate of 7G% can obtain the thermal insulation effect with 嶋. Furthermore, the coverage rate is 80%. At this time, large-sized vacuum insulation materials can be used to cover the sides, top, back, silk, and front surfaces of the box. 20

Therefore, it is possible to close the standard state of the vacuum heat insulating material, or to perform the installation work that is part of the operation efficiency, and the cost performance becomes good. That is, there is no collapse in the balance between the increase in the cost of refrigerators and materials and the cost due to energy saving due to the application of the _ «. Therefore, it is possible to increase the value as a% cost of life cycle. In addition, if it is installed from the place where the thermal steepness inside and outside the thermal insulation box is large, if 14 200300343 sets the coverage to be more than 50% of the surface area of the external box, the heat absorption load of the thermal insulation box can be effectively suppressed to increase energy saving effect. In addition, in terms of investment efficiency, the contribution rate to energy costs is large in the range of 50% to 70%. 5 For this reason, due to the structure of the vacuum insulation material disposed on both sides, top, back, bottom, and front of the refrigerator 10, the coverage rate of the surface area of the vacuum insulation material to the outer box is 50% to 80%, and more than Below 70 is ideal. In addition, the steepness of the internal and external temperature 10 of each of the lintels 27, 28, 29, 30, and 31 is smaller than that of other parts of the adiabatic cabinet that are related to heat dissipation such as the mechanical room 20. In addition, the strength of the contents stored inside the library supported by each door lintel or the strength of the mechanical detachment of the lintel switch facing the vacuum insulation material becomes necessary. From these facts, it is also considered to control the arrangement of the vacuum insulation materials towards each door, so as to effectively obtain the applicable effect of the vacuum insulation materials in the other body parts of the insulation box. 15 At this time, the coverage rate of the vacuum insulation material is about 53% at a height of 1800 mm, a width of 675 mm, and a depth of 650 mm, and it becomes an energy-saving refrigerator suitable for a reasonable vacuum insulation material with an adhesion area of 50 to 80%. . Furthermore, the vacuum insulation materials 32, 33, and 34 are arranged on the outer surface of the outer box 11. The average roughness (Ra) of the centerline of the outer surface of the outer box 11 is set to 0.1 micron or more, and the fixed ratio is set to 20 or less. · 1 micron thick. A manufacturing method of the refrigerator compartment door 27 is demonstrated using FIG.4 and FIG.5. The lintel inner panel 42 has a projecting portion 43, and a vacuum heat insulating material 38 is attached to a surface connected to the frontmost portion 44, for example. Then, after the polyurethane foam material 13 is injected into the inside of the lintel outer panel 27A, the lintel inner panel 42 is covered and foamed to form the lintel 27. 15 200300343 # 者 ’Figure 6 is a sectional view of the draw-out cold; The door has an inner panel of 45〃 and a solid base.卩 47 is a guide rail 46 for holding and supporting a box (not shown) for storing frozen food. Moreover, the polyurethane foam material_reinforcing plate ^ is fixed by the fixing portion 47 of the lintel inner panel 45 and the guide 46. The partition 49 is the space part where the real work and heat-reducing material 41 S has been placed on the inner part of the inner panel 45 and the outer panel of the door. 15 20 = Point composite materials are fixed to the _ part of the reinforcing plate 48 . The partition plate 49 is composed of a vacuum bar, a material 41 * | human, such as foamed styrene or polyethylene foam material 2, and the partition plate 49 has a slightly rectangular parallelepiped shape. The flow direction of the foamed material 13 at the time of foaming is arrange | positioned like a separator. The cooling unit is composed of a compressor 21, a refrigerating cooler 22, a refrigerating fan 23 ~ 4, a cooler 24, and a cooling device; an east blower and a condenser 26 constitute a cooling device. Such a cooling device, the refrigerating compartment 15, and the vegetable compartment 16 are approximately 0 to 10 degrees Celsius, the changing room 17, the ice maker, and the cold beam magic 9 are cooled to a temperature of approximately 15 to 25 degrees Celsius. In addition, if the thermal insulation material is arranged in a place with a large thermal steepness inside and outside the cabinet, if the coverage ratio becomes 50% or more of the surface area of the cabinet, the heat absorption load of the refrigerator can be effectively suppressed. Therefore, the energy saving effect can be improved. Also, because the coverage rate is made as below, it becomes possible to avoid the use of a vacuum insulation material as a standard external form or the installation operation towards a part with poor working efficiency. Also = It can avoid the reduction of the heat absorption relative to the vacuum insulation material and the cost ratio = Li Er Vacuum insulation material effectively suppresses the absorption Λ, and the negative 1 in the state of high use value, which can improve the energy saving effect. The vacuum insulation materials 32, 33, and the insulation material n 4 are connected to the outer box η, and the unevenness of the unevenness, bending, and other flatness of the surface of the vacuum ... 4 is unevenly hooked. 16 200300343 Mainly deformed on the outer surface of the outer phase 11 Possibility. However, because the average coarseness of the centerline of the outer surface of the outer phase 11 (referred to as more than 0.01 micron) is set to be coarser than conventional products, the reflectance of light on the outer surface of the outer box of the same-coating material is reduced. As a result, the visibility is reduced. The deformation of the outer surface of the outer box caused by the vacuum insulation ㈣ * 5 attached. Therefore, the complex structure or special |. Pieces, without using materials, can be deformed in accordance with the appearance of the refrigerator to which the vacuum insulation is applied. The upper limit of the average thick chain degree 线 of the center line of the outer surface of the box 11 is desirably within 1 micron without deteriorating the appearance. Furthermore, the surface connecting the foremost portion 44 of the inner panel 42 of the lintel is affixed with true Φ 10 and is absolutely empty After the hot material 38 is injected into the polyurethane foam material 13, the inner panel 42 of the door is covered to make the foam form the door 27. Therefore, the vacuum heat insulating material S8 is not directly connected to the outside of the door 27, and no The urethane foam material 13 shrinks after foaming, which causes deformation of the outside of the refrigerator compartment door 27. Furthermore, the vacuum insulation material 38 is attached to the surface of the door 44 such as the foremost portion 44 of the inner wall 42 of the door, which can maximize the maximum Bigger configuration The vacuum heat insulating material 38 can be used to improve the thermal insulation performance of the south. In addition, the large raised portion 43 formed on the inner side of the inner panel of the door lintel 42 is also filled with the amino heat insulation material of the vacuum heat insulating material 38 and the space portion of the door inner lining 42. The ester foam material 13 enhances the strength of the protruding portion 43. Furthermore, the vacuum insulation 4 provided on the door panel 31 and the part through the partition 49 is disposed between the door panel inner panel 45 and the door panel outer panel 50. The space part. Therefore, deformation of the outer surface of the door outer panel 50 due to the foaming contraction of the polyurethane foam material 13 will not occur. The fixing part of the guide 46 formed in the door inner panel 45 47 or near the reinforcing plate 48, and also form a polyurethane foam material 13, which can increase the strength of the guide fixing portion 47. 17 200300343 In addition, the partition plate 49 is made into a slightly rectangular parallelepiped shape. Γ: 料 13 Flow direction during foaming and _ ^ Therefore, reducing the barrier 49 to hinder the polyurethane, Bu s * ~ ㈣ cutting material 13 when flowing foam back to the urethane filling, indeed & _ _ The increase of the ㈣ fixed part 47 In addition, although it is explained about the pull-out door of the refrigerator according to this embodiment, The beam chamber ㈣3. For the vegetable chamber 构成 constituting the pull-out door 扉, the switching chamber door 29 is also effective as the same structure. 10 Furthermore, as described above, the single-vertical heat insulating material 38 is used for the refrigerator door 扉 27. However, as shown in FIG. 7 and FIG. 8, it is also possible to arrange a plurality of straight air insulation materials 38A of Menmo, and connect the Menmo inner panel, leaving a gap near the protrusion 43. More specifically, the polyurethane foamed material 13 'can improve the strength of the protrusion of the refrigerator compartment door 427β. 15 (Embodiment 2) The basic structure of the refrigerator according to Embodiment 2 of the present invention is the same as that of Embodiment 1. In Embodiment 1, the center line average roughness of the outer surface of the outer box is defined. In the present embodiment, the vacuum heat insulators 32, 33, and 34 are arranged on the outer surface of the outer case 12. The light height of the outer surface of the outer case 12 is reduced from the conventional 90 degree, and the gloss is reduced to 80 or less. Here, the glossiness refers to a reflectance of 10% when the refractive index is 1.567 on a glass surface at an incidence angle of 60 degrees, or the reflectance at a incidence angle of 20 degrees is 5❻ / 〇. Industrial Standard) (Japanese Industrial Standard B 8741). 200300343 Similar to the first embodiment, the vacuum insulation materials 32, 33, and 34 are connected to the outer case 12 and attached. Therefore, due to irregularities such as unevenness and curvature of the surfaces of the vacuum insulation materials 32, 33, 34, etc., the outer surface of the outer case 12 may be deformed. Here, since the outer surface gloss of the outer box 12 is 5 80 or less, the same surface roughness reduces the light reflectance of the outer surface of the outer box. Therefore, it is possible to reduce visually the deformation of the outer surface of the outer box caused by the application of the vacuum insulation material. Therefore, a complicated structure or a special part can be deformed in accordance with the appearance of the refrigerator 10 to which a vacuum insulation material is applied without using a material. In addition, the outer box

12 The gloss of the outer surface can be expected to be 10 degrees without deteriorating the appearance. (Embodiment 3) FIG. 9 is a side view of a main part of a refrigerator according to Embodiment 3 of the present invention, and FIG. 10 is a perspective view of the same part. Basic structures other than these are the same as those of the first embodiment. Figure A 15 20

Between the head I and the inner box 52, a soft member & an empty heat insulating material 54 and a rigid polyurethane foam material μ as intermediate members are provided to prevent deformation of the outer surface of the outer box from the side of the box 51. The soft member is larger in size than the vacuum heat insulator, and is preferably a softer member than the vacuum heat insulator 54. A resin foam composed of, for example, an independent foam is desirable. The thickness U of the soft member 53 is preferably equal to or larger than the plane of the vacuum heat insulating material 54 and less than or equal to the thickness of the vacuum heat insulating material. Bahong is made of j. In the above structure, it is installed on the vacuum insulation material μ and the outer box member 53 tree wheel—by y material 4 19 200300343 unevenness of flatness such as unevenness and bending is absorbed, which can prevent the outer surface of the outer box. Deformation. Furthermore, if the soft member 53 is larger than the vacuum absolute heating material 54, the mounting deviation when the vacuum insulation material 54 is affixed to the outer case 51 is absorbed, which improves the work efficiency. 5 Furthermore, if the soft member 53 is a member that is softer than the vacuum insulation material 54, the outer covering of the vacuum insulation material 54 will not be damaged during manufacture, and the reliability of the vacuum insulation material 54 will be improved. When the soft member 53 as the intermediate member is a member made of a resin foam member, when a rigid polyurethane foaming material (hereinafter, polyurethane 10 acid S purpose foaming material) 13 is foamed, The foaming pressure is absorbed due to the compression of the resin foam. In addition, the shrinkage of the foamed polyurethane foam is absorbed by the expansion of the resin foam, which can reliably prevent the outer surface of the outer box from being deformed. In addition, if the flexible member 53 is a member composed of an independent foam, it is possible to prevent gas such as foam gas or air from entering the flexible member 53 and to prevent deformation of the outer surface of the outer casing due to temperature change. The thickness t1 of the soft member 53 is equal to or greater than the flatness of the vacuum heat insulating material 54 and less than the thickness of the vacuum heat insulating material, and more specifically 3 mm to 15 mm. Therefore, the flatness of the vacuum heat insulating material is uneven, and the soft member can surely absorb it, and the soft member 53 is not required to be 20 degrees thicker than necessary, so that the heat insulating performance is not reduced. In addition, even if the soft member 53 is affixed to the outer case 51 and the vacuum heat insulating material 54 is affixed, the soft member 53 may be affixed to the vacuum heat insulating material 54 in advance and then affixed to the outer box 51. (Embodiment 4) 200300343 Fig. 11 is a sectional view of a main part of a side wall of a refrigerator according to Embodiment 4 of the present invention. The basic structure is the same as that of the first embodiment. The hard member 56 provided between the vacuum heat insulating material 54 and the outer case 51 as an intermediate member is made of a member that is harder than the vacuum heat insulating material 54. For example, it is composed of a 5 ABS (copolymer of acrylonitrile, butadiene, and styrene) sheet, and its thickness is equal to or less than the flatness of the vacuum heat insulating material 54. Specifically, it is preferably equal to or less than 3 mm. According to the above structure, it is possible to prevent the main causes of deformation of the outer case such as unevenness and warpage on the surface of the vacuum heat insulating material 54 from being transmitted to the outer surface of the outer case, and to prevent the outer case surface 10 from being deformed. In addition, since the thickness of the hard member 56 is relatively thin, it is possible to suppress the influence on the heat insulation performance. (Embodiment 5) Figure 12 is a sectional view of a main part of a side wall of a refrigerator according to Embodiment 5 of the present invention. The other basic structure is the same as that of the first embodiment. In the figure, a soft member 53 and a hard member 56 are arranged between the vacuum heat insulating material 54 and the outer box 51. The arrangement order is from the outer case 51 side, the hard member 56, the soft member 53, and the vacuum heat insulator 54. According to the above structure, the soft member 53 absorbs the main causes of deformation of the outer box such as unevenness and bending on the surface of the vacuum heat insulating material 54, and the hard member 56 prevents the main causes of deformation of the outer box, and can reliably prevent the outer surface of the outer box from deforming. Furthermore, as the intermediate member, since the hard member 56, the soft member 53, and the vacuum insulation material 54 are arranged in this order from the outer case 51, it is possible to prevent damage to the outer material of the vacuum insulation material caused by the soft member 53. (Embodiment 6) 200300343 Figures 13 to 15® are sectional views of various vacuum insulation materials used in refrigerators according to embodiments of the present invention. Basic structures other than these are the same as those of the first embodiment. The core material 5 7 sealed inside the vacuum insulation material is sealed with an i-th outer covering material 5 8 around the inside, and the interior is evacuated after being exhausted. Further, the outer periphery of the first duvet material 58 is covered with the second outer duvet material 59 as a double-layer structure. In Fig. 13, the space 60 between the first outer covering material 58 and the second outer covering material 59 is filled with gas. As the gas system, air or an inert gas is used. In this way, the outer periphery of the first outer covering material 58 which deforms the outer case of the core material 57 enclosed in the vacuum insulation material, such as concave, convex, or curved, is covered with the second outer covering material 59 as a double-layer structure. Thereby, the second outer cover material 59 absorbs the deformation factor of the outer box, and prevents the outer surface of the outer box from being deformed. In addition, a gas is enclosed between the outer covering materials 58 and 59 having a double-layer structure. Therefore, the gas space between the outer covering materials 58 and 59 enclosed in the double-layer structure absorbs the deformation and deformation of the outer case such as the unevenness and curvature of the surface of the vacuum insulation material, and prevents the outer surface of the outer case from being deformed. Furthermore, as shown in FIG. 14, the thickness t3 of the outer covering material 59B having a double-layer structure is made thicker than the thickness t2 of the other outer covering material 59A, and the outer covering material 59B side may be attached to the outer case 12. In this case, since the outer cover 59B is thicker in thickness t3, the thickness t3 absorbs the contours of the outer box such as the unevenness and curvature of the surface of the vacuum heat insulating material, thereby preventing deformation of the outer box surface. Furthermore, as shown in Fig. 15, the outer periphery of the first outer covering material 58 is covered with the second outer covering material 59 as a double-layer structure, and a soft member 61 may be enclosed between the outer covering materials having the double-layer structure. In this case, the soft member 61 absorbs deformation factors of the outer case such as unevenness and curvature on the surface of the vacuum heat insulating material, and can prevent deformation of the outer surface of the outer case. Also, 22 200300343 The soft member 61 has a protective effect of the vacuum insulation material, and improves the reliability of the vacuum insulation material. (Embodiment 7) ~ Fig. 16 is a plan view of a refrigerator outer box before bending according to Embodiment 7 of the present invention. · Your plan view. Chu — ^ The figure shows an oblique view of the refrigerator after the outer box is bent. · ~ The figure is a cross-sectional view of the main part of the vacuum insulation material used in the same refrigerator. The ninth figure is the enlarged cross-sectional view of the part of the vacuum insulation material used in the same refrigerator. After the bubble _ with the other _ end main ^ knife solution oblique view. Basic structures other than these are the same as those of the first embodiment. The outer box composed of 5 panels is called to fold a flat panel before folding. In the outer box 62, a heat-dissipating tube 63, which is circulated in a bundle, is fixed with a belt 64 as a fixing member, and the vacuum insulation material 65, 66, 67 is fixed on it with a thermal fusion transfer member. When he died, the outer box 62, the back plate 7G, the bottom plate 71, and the inner phase (not shown) were bent by the bent portion 69. After that, the space formed by the outer box 62 and the inner box is filled with a beryllium female base acid foaming material to be foamed. Therefore, the mechanical chamber component 68 of the compressor or the like that houses the refrigerator cannot be filled with polyurethane packaging material and communicates with the outside. In addition, the adhesive tape 64 for fixing the heat dissipation pipe 63 is extended to the mechanical room component 68. The other end 64B of the Lu tape 64 is formed inside the vacuum heat insulating material. In addition, the vacuum insulation material 65 is formed by the press-in portion of the press 72 after the completion thereof. The groove is formed. The vacuum insulation material 65 is arranged and fixed to the outer case 62 so that the groove 74 enters the heat radiation pipe 63. When a heat radiation pipe 63 is arranged between the outer box 62 and the vacuum heat insulating material 65, a first gap portion 76 is generated between the outer box 62 and the tape 64. A second gap portion 77 is formed between the aluminum tape 64 23 200300343 and the groove 74 of the vacuum heat insulating material 65. : With the above structure, because the voids 76, 5 10 15 hurt 164A, and there is no retention of gases such as foaming gas in the voids 76, 77, _ temperature changes, voids The parts 76 and 77 do not prevent deformation of the outer surface of the outer case 62 where the heat pipe 63 is provided. I can

=, ‘64A of 64’ is extended to the machine room ’s structural unit and repaired, so that the other end is located in a position more than the end of the vacuum insulation material 65. When the rigid acetic acid foam material 75 is foamed, the gap between the vacuum insulation material M and the heat sink & 63 invades a little polyurethane. However, as shown in Fig. 20 *, with this structure, the other end 64B of the turn belt 64 has not been reached. Therefore, since the void portion% near the other end 64B side of the aluminum tape 64 communicates with each other, the gas in the void portions 76 and 77 can be smoothly discharged from the body. Accordingly, the space portion does not expand or contract due to changes in ambient temperature, and the outer surface of the outer casing 62 outside the arranging portion of the radiating tube 63 can be reliably deformed.

Further, the groove 74 formed in the vacuum heat insulating material 65 with respect to the heat dissipation pipe 63 is formed by the press-in portion 73 of the press 72 after the vacuum heat insulating material 65 is completed. Therefore, it is necessary to provide grooves in the core material of the vacuum insulation material 65 in advance, so that the manufacturing steps of the vacuum insulation material can be simplified. 20 In the above description, although the aluminum tape is used as the fixing member, the material is not particularly limited as long as it is an adhesive tape material having adhesiveness. And it is more ideal if there is thermal conductivity. (Embodiment 8) Fig. 21 is an enlarged sectional view of a main part of a refrigerator according to Embodiment 8 of the present invention. The basic structure is the same as that of the first embodiment. In the outer surface of the outer box 62, a small hole 78 provided in advance by a press or the like is an arrangement portion corresponding to the vacuum heat insulating material 65, and a plurality of straight holes are provided in the outer box 62. The gas in the space between the vacuum insulation material 65 and the outer case 62 in the above-mentioned structure becomes a main cause of deformation of the outer case due to the unevenness and curvature of the surface of the vacuum insulation material 65. The gas can be smoothly discharged out of the refrigerator through the fine holes 78. Therefore, the space portion does not swell or shrink due to a change in ambient temperature, and deformation of the outer surface of the outer case 62 outside the arrangement portion of the vacuum heat insulating material 65 can be prevented. In addition, the arrangement of the fine holes 78 is not limited to straight, curved, and polygonal shapes. (Embodiment 9) Fig. 22A is a cross-sectional view of a part of the left side viewed from the right side when the left and right sides of the refrigerator are cut according to Embodiment 9 of the present invention. Figure 23A is a cross-sectional view of the state of the rear part when viewed from the front when the refrigerator is cut in front and rear. 15 According to Ben Bescher, the basic structure of the refrigerator is different from that of the first embodiment in the method of arranging a vacuum insulation material. That is, the vacuum insulation materials 32, 32a, 33B, and 34 are connected to the top φ, the back surface, and the upper side of the outer box π, respectively, and affixed to them. In addition, the vacuum insulation materials 35, 34A, and 36 are connected to the bottom surface, the lower side surface of the inner box, and the structural surface of the machine room 20, respectively. Further, inside the refrigerator door 10, refrigerator room door 28, vegetable room door 28, and freezer door 29, 31, which are arranged in front of the refrigerator 1020, vacuum insulation materials 38, 39, 40, and 4 are connected to each other. The outer iron plates of each lintel are arranged like this. According to this embodiment, each vacuum heat insulating material is arranged from a place passing through the heat insulation box with a large thermal gradient inside and outside, and the bottom surface and the machine room 20 are connected to each other. 25 200300343 The inner box 11 is arranged. Therefore, the vacuum insulation materials 35, 34A, 36, and 37 arranged on the lower side surfaces, the bottom surface, and the machine chamber 20 of the outer box 12 whose temperature becomes high will not be exposed to high temperatures. Therefore, it is possible to minimize the deterioration of the vacuum insulation performance at all times and to improve the long-term reliability of the vacuum insulation materials 35, 34A, 36, and 37. In addition, since the vacuum heat insulating material 34A on the side of the lower rain is arranged to connect to the inner box 11, avoiding the complicated fitting part or piping between the outer boxes 12, the vacuum heat insulating material 34A can be prevented from being damaged. That is, when the shape of the outer box 12 becomes complicated on both sides of the lower part, since the vacuum heat insulating material 34A is connected to the inner box 11, the reliability is improved. Furthermore, since the top surface of the vacuum heat insulating material 32 is connected to the outer box, it becomes possible to mount a lighting installation member or an electric wire (not shown) in the room to the top surface of the inner box 11. Therefore, lighting can be provided on the top surface of the refrigerating compartment 15 to improve convenience in use. 15 Also, since vacuum insulation materials 33A and 33B are provided on the back of the heat insulation box, these vacuum insulation materials will not become piping that hinders the cooling device or defrosting water drainage pipes (not shown) that discharge the cooling lines 22 and 24. situation. In addition, the back plate and the vacuum heat insulating materials 33A and 33B can be assembled as a whole, which is preferable in terms of manufacturing steps. 2〇 Furthermore, since each vacuum insulation material is connected to one of the outer case 12 and the inner case 11 constituting the heat insulation box of the refrigerator, the rigid polyurethane foam material of the resin foam body can be fully ensured. 13 the spatial distance formed. Therefore, the thermal insulation performance does not decrease due to cracking or insufficient foaming of the polyurethane foam 30, and the strength and appearance of the cabinet are maintained good. 26 200300343 The insulation thickness of the insulation boxes forming the freezing compartments 18A and 19 in the freezing area and the insulation boxes forming the refrigerating compartment 15 and the vegetable compartment 16 in the refrigerating area are the same as in the first embodiment, and the description is omitted. The same applies to the coverage of the outer surface of the refrigerator 10. 5 In addition, the vacuum heat insulating materials 33A and 33B are arranged on the back panel in advance, and the side surface and the top surface formed by folding the plane into a J shape are joined to form the outer case 12. At this time, it is preferable that the vacuum heat insulating materials 33A and 33B are arranged near the interfaces forming the outer box 12. That is, the vacuum heat insulating materials 33A and 33B are configured to be approximately the same size as the back plate. This improves the thermal insulation performance. 10 Furthermore, it is preferable to arrange each vacuum insulation material in the outer box 12 or the inner box 11 in advance. Doing so makes it easy to assemble the box. Furthermore, it is preferable that the vacuum insulation materials 35, 34A, 36, and 37 provided to the inner box 11 have a smaller projected area than the inner box 11. In other words, the vacuum heat insulating materials 35, 34A, 36, and 37 provided in the connection inner box 11 are not exposed from all sides of the inner box 11 provided in connection with the vacuum insulation 15 materials 35, 34A, 36, and 37. In such a structure, after the vacuum heat insulating materials 35, 34A, 36, and 37 are arranged in a certain place, polyurethane foam material flows between the outer box 12 and the inner box 11. At this time, no force is applied to the vacuum insulation material 35, 34A, 36, 37 disposed in the inner box 11 from the inner box 11 in the direction of peeling. Therefore, 20 can prevent the vacuum insulation material 35, 34A, 36, 37 from being peeled off due to the inflow of the polyurethane foam material 13. Furthermore, the vacuum insulation materials 35, 34A, 36, and 37 can be easily and stably attached without impairing the fluidity of the polyurethane foam material 13. Furthermore, the surface of the inner box 11 200300343 connected to the vacuum insulation materials 35, 34A, and 36 is provided with a convex portion 11A 'surrounding the outer periphery of each vacuum insulation material as shown in FIG. 23B or as shown in FIG. 23C. It is shown that the recessed portion 11B containing each vacuum heat insulating material is preferable. Each of the convex portion ilA and the concave portion UB has a portion connected to the outer periphery of the vacuum heat insulating material. Due to the section, the exposed area of the end face of each vacuum insulation material is reduced. Since the segments are provided in this way, the positions can be easily determined when the vacuum insulation materials 35, 34A, and 36 are adhered, and the vacuum insulation materials can be prevented from being damaged. In addition, since the polyurethane foam material 13 flows in, it is possible to prevent peeling of each of the vacuum insulation materials. In addition, the step difference between the inner box 11 and the vacuum heat insulating material 35, 34A, and 10 36 is reduced without the convex portion 11A, and the fluidity of the polyurethane foam material 13 is not impaired. If there is no recessed portion 11B, the mold processing of the inner box u will be easy. Moreover, the segment itself becomes a reinforcement of the inner box η, and it is easy to attach the vacuum heat insulating materials 35, 34A, and 36. In addition, when the vacuum heat insulating material 36 is arranged at the lower part of the cooler 24, a heat insulating member 36A is arranged at the lower part of the cooler 24 or the inner surface of the inner box 11 as shown in FIG. A certain oblique shape is formed on the upper surface of the heat insulation member 368 for treating defrosting water, and the lower surface is formed in a flat shape and is attached to the inner box U. In addition, a hole is provided at the lowermost part of the heat insulation structure 36A, and a path for removing defrosting water from the hole to the outside is provided. 20 As the heat insulating member 36A, the surface of the inner box 11 below the cooler 24 becomes flat. Since there is no inclined portion on the surface of the inner box 11, the vacuum insulation material 36 can be effectively stuck. The inflow of the polyurethane foam material 13 prevents the vacuum insulation material 36 from peeling off. In addition, since the portion to which the vacuum heat insulating material 36 is attached is not inclined but has a flat surface and the side length becomes shorter, the vacuum heat insulating material 36 can be made smaller. 200300343 As the side length becomes shorter, the heat absorption load towards the refrigerator can be reduced. In the above description, the inner surface of the inner box 下方 below the cooler 2 4 provided with the heat insulating member 3 6 A is a flat surface. However, the lower surface of the cooler 24 in the inner box 丨 丨 serves as an inclined surface, and a heat insulating member 36A may be provided outside a part of the inner box 丨 丨. In this case, the vacuum heat insulating material 36 is arranged in the heat insulating member 36A in advance, and it is possible to assemble the cabinet and manufacture it easily. Furthermore, as shown in Fig. 23A, it is preferable to provide the exhaust hole nc of the polyurethane foam material 13 inside the inner case 11. Due to such a structure, a vent hole is not required on the back surface of the outer case 12, and a vacuum heat insulating material 33A can be provided. On the other hand, 10 ' becomes a non-exhaust hole in the outer box 12 to ensure a beautiful appearance. In addition, it can be used as the back of the outer box of refrigerators with other structures, reducing the number of parts and labor. Furthermore, as shown in Fig. 23A, the boundary portion of the vacuum heat insulating material 34 and the vacuum heat insulating material 34A is preferably a laminated structure of the vacuum heat insulating material 34 and the vacuum heat insulating material 34A. In this embodiment, the position of the lower end of the vacuum heat insulating material 34 provided to the outer box 12 on both sides of the upper side of the refrigerator 10 is lower than the position of the upper end of the vacuum heat insulating material 34A provided to the inner box η on both sides of the lower side. When vacuum insulation materials 34 and 34A are provided on both sides of the refrigerator, there may be deviations in the vertical direction. In addition, the dimensional accuracy of the vacuum heat insulators 34 and 34A may be low. In this case, there are two sides of the refrigerator 10, and at least one of the outer box 12 and the inner box 11 also has a vacuum insulation material. Therefore, the thermal insulation effect of the vacuum insulation materials 34 and 34A is not impaired. Furthermore, the flow of the polyurethane foam material 13 is not hindered, and stable flow can be performed. Furthermore, in order to easily and effectively attach the vacuum heat insulating materials 35 and 36, it is preferable that the inner box 11 is flat in the width direction. In this embodiment, a flat inner inner box 11 is formed on the outside of the bottom surface of the refrigerator 10 in the width direction of 29 200300343, and is connected to the vacuum heat insulating materials 35 and 36. Due to this structure, the adhesion area of the vacuum insulation materials 35 and 36 on the bottom surface of the inner box U can be enlarged, and the area of the bottom surface can be reduced. Can improve energy efficiency. Furthermore, the adhesiveness of the vacuum heat insulation materials 35 and 36 is improved. -In addition, when vacuum insulation materials 32, 33A, 33B, 35, 34, 34A, 36, 37, 38, 39, 40, and 41 are provided, it is ideal to remove foreign matter from the adhesive surface before attaching. In this embodiment, before the vacuum insulation materials are attached, the foreign matter on the surface connecting the vacuum insulation materials is removed. As a result, the absence of foreign matter can prevent the vacuum insulation material from being damaged, and the reliability of the bonding step can be improved. Lu (Embodiment 10) FIG. 24 is an enlarged cross-sectional view of a main part of a vacuum insulation material to which the refrigerator of this embodiment is applied. Fig. 25 and Fig. 26 are enlarged views of the wearing surface of the refrigerator according to the same embodiment. The basic structure of the entire refrigerator is the same as that of Embodiment 9 or Embodiment 9. The vacuum insulation material 91 has a core material 92 inside. The core material 92 is composed of a glass wool two inorganic fiber aggregate. The vacuum insulation material 91 is formed by heating and drying the core material 92 without being inserted into the laminated material 93 and the metal H-layer film 97, and is formed by evacuating the inside and sealing the opening. s steamed money layer is thin and mixed _95 is a thin plastic film with a thin film of 96 sandwiched by Gao Niu and Gao Niu. Metal Delaminated Film 97:-Difficulty 99 with nylon film 98 and high-density polyethylene mi00 plastic film. "In addition, the sealing surface of the vapor-deposited layer film 93 and the metal junction layer_97 is a three-dimensional shape with the thin-plated side of the strip plating layer, and the surface 30 200300343 of the metal film layer is three-dimensionally formed. The plating film 93 is connected to the outer box 12 or the inner box 11. That is, the vacuum heat-insulating material 91 is a flat surface that requires high heat insulation, and is composed of a vapor-deposited film 93 having an aluminum vapor-deposited film 95. On the other side, which requires high gas barrier properties, it is composed of a metal foil layer film 97 having a metal foil 99-5. The sealing surfaces of the two films 93 and 97 are placed on the same plane as the plane on the vapor deposition layer film 93 side. Due to such a structure, it is possible to handle the burr of the sealing surface easily, and at the same time, the vacuum heat insulation material 91 having high reliability and excellent heat insulation performance is shown in Figs. 25 and 26. Arrange the 93-side flat surface of the vapor-deposited film 91 of the real 10-space insulation material 91 to the inside of the outer box 12 or the outside of the inner box 11. Thus, it is possible to effectively arrange a vacuum insulation material 91 having high reliability and excellent absolute performance, and a sealing surface. No need to deal with burrs In addition, the inner box 11 and the outer box 12 are the same on both sides and cannot be affixed with a vacuum insulation material when the shape is complicated. In addition, where the reliability of the vacuum insulation material becomes important, a vacuum with a metal foil film on both sides is used. Insulation materials. Since the double-sided film constituting the vacuum insulation material uses a metal foil film with high gas barrier properties, even when both sides of the vacuum insulation material are connected to a complicated shape surface, a highly reliable vacuum insulation material can be used. Since the two sides are made of the same material, the cost can be reduced. Moreover, since the two sides are made of the same material, when the outer box 12 or the inner box 11 is affixed, there is no worry that the vacuum insulation material is adhered to the surface, and the operation becomes easy. The fiber diameter of the inorganic fiber assembly constituting the core material 92 is in the range of 0.1 micrometer to 1.0 micrometer. Compared with the thermal conductivity of the rigid polyurethane foam material 13, it has a thermal conductivity of about 1/10. A vacuum insulation material of 200,300,343 is preferable. The thermal conductivity of the polyurethane insulation material 13 is 0.015 watts (T) per meter of material, then the heat conduction system of the vacuum insulation material 91. 〇15 watt (T) / mK. The thermal conductivity of the vacuum insulation material 91 depends on the fiber diameter of the inorganic fiber assembly. (Special) / Mika. That is, the thermal conductivity of the polyurethane_foam material 13 may be in the range of 1/15 ratio. This is between the polyurethane foam material 13 and the vacuum insulation material 91. When the thickness of the multi-layer insulation wall is relatively thin, in order not to hinder the fluidity of the polyurethane foam material 13, even if the thickness of the vacuum insulation material 91 is reduced, it is to effectively exert the heat insulation performance of the multi-layer insulation wall. In addition, in order to achieve a high coverage rate, a true thermal insulation material is also arranged in a relatively thin place, so as to exert energy saving effects as expected. (Embodiment 11) Fig. 27 is an enlarged sectional view of a main part of a refrigerator according to an embodiment u of the present invention. The other structure is the same as that of the first embodiment. In the figure, the outer cover material of the vacuum insulation material 79 is composed of a film 80 having an aluminum vapor layer on one side and a film structure having a notch on the other side. The film 80 is attached to the outer box 62. Further, the sealing portion 82 of the film 80 and the film 81 is arranged on the side of the rigid polyurethane foam material by bending. In the above-mentioned structure, although the film 80 having an aluminum vapor-deposited layer has a low thermal conductivity, 20, the gas permeability is larger than that of the film. In addition, the thin film 81 having thorium has a low gas permeability, but has a higher thermal conductivity than the thin film 80. Therefore, the side of the film 81 where heat conduction is easy, that is, if the sealing portion 82 is bent on the side of the polyurethane foam material 75, the heat transfer path of the film 81 toward the heat of the outer box will be long. The distance between the sealing portion 82 and the outer box 62 is increased. Since 32 200300343 and the like, it is possible to suppress heat transmission through the film to the outer box 62 side, and to improve heat insulation. In the above description, although the thin film having an aluminum vapor-deposited layer and the thin film having a single metal foil have been described, they may be made of other metals. In addition, although the first embodiment is basically described as the present embodiment, it may be combined with the features described in the other embodiments. The features of this combination in the following embodiments will also be good. (Embodiment 12) FIG. 28 is a cross-sectional view of a refrigerator according to Embodiment 12 of the present invention. Fig. 29 is an enlarged view of a part near the radiator tube of the refrigerator. Structures other than those described above are the same as those of the first embodiment or the ninth embodiment. Forming a part of the refrigeration cycle, the heat dissipation tube as the condenser is connected to the side or the back of the outer box I2, and is fixed to the outer box 12 by an aluminum tape 102 with a high thermal conductivity. The aluminum tape 102 serves as a sealing material. A vacuum heat insulating material 34 is provided on the cover like the heat radiating officer 101. The aluminum tape 102 is disposed outside the refrigerator 15. Due to such a structure, the heat of the heat-radiating tube 101 is reliably insulated by the vacuum heat insulating material 34 to effectively reduce the heat absorption load into the refrigerator. In addition, since the aluminum tape 102 is disposed outside the refrigerator, the air between the heat dissipation tube 101 and the outer case 12 can be moved toward the outside of the refrigerator at will. As a result, unevenness or undulations on the surface of the outer case I2 caused by thermal contraction of the air can be suppressed, and the appearance is maintained. In addition, there is no concern about the amount of air between the heat pipe 110 and the outer box 12, and the sticking operation of the heat pipe ⑻ can be easily performed. It is also preferable that the 'Ming tape H) 2 is divided or has no holes on the way. As a result, the air between the heat sink 101 and the vacuum heat insulating material 34 can also be moved toward the outside of the refrigerator at will. Therefore, the surface of the outer box 33 200300343 12 caused by thermal contraction of the air can be suppressed, and the appearance of the outer box can be maintained. In addition, there is no need to worry about the amount of air between the heat pipe 101 and the vacant heat insulator 34, and the sticking operation of the heat pipe 101 can be easily performed. In addition, when the heat-radiating pipe 101 is provided, the vacuum heat-insulating material 34 is incorporated in advance, and 5 may be placed in the outer case 12. In this case, a vacuum heat insulating material 34 which incorporates the heat radiating tube 101 on the side connected to the outer case 12 is disposed inside the outer case 12. If so configured, instead of sandwiching the heat pipe 101 between the outer box 12 and the vacuum heat insulating material 34, it is better to reduce the gap between the heat pipe 10 and the vacuum heat insulating material 34 before fixing the heat pipe 101 inside the outer box 12. Therefore, the surface of the outer case 12 is suppressed from being raised or lowered by 10 volts, and the beauty of the appearance can be maintained. Increasing the thermal insulation effect of the vacuum insulation material 34 can increase the energy saving effect. In addition, since it is possible to assemble the heat pipe 100 in the vacuum heat insulating material 34 in advance, it is easy to manufacture. In the above structure, the heat radiating pipe 101 is sandwiched between the outer case 12 and the vacuum heat insulating material 34 and is attached. The vacuum heat insulating material 34 can surely insulate the heat 15 of the heat radiation pipe 101, which can effectively reduce the heat absorption load into the refrigerator. (Embodiment 13) Fig. 30 is an oblique view of a refrigerator outer box flat plate according to Embodiment 13 of the present invention, before being folded. The other basic structure is the same as that of the first embodiment or the ninth embodiment. 20 Government hot moss 1 〇 1 『The surface 1 107 connected to the side surface of the outer box 12 is provided, and the heat radiation pipe 61 is not arranged on the surface 106 which becomes the surface. In other words, the heat radiating tube 101 is disposed inside the outer case 12 away from the place where it becomes the top surface of the refrigerator. Due to such a structure, the heat of the heat sink tube 101 is reliably insulated with the real heat-reducing material 34, which can reduce the heat absorption load into the ice phase. In addition, since the vacuum heat insulating material has better heat insulation performance than rigid polyamine 34 200300343 urethane foam material 13, it can reduce the heat absorption amount of the refrigerator, and the top surface 106 can be provided without the heat pipe 101. Therefore, the vacuum insulation material 32 can be easily attached to the top surface, and the energy saving effect can be improved. In addition, since the heat radiation pipe 101 is not provided on the top surface 106, the shape of the heat radiation pipe 101 is simplified, and the workability can be improved, the number of processes can be reduced, and the material cost can be reduced. Moreover, since the heat radiation pipe 101 is not provided on the top surface, it can also be used as a heat radiation pipe for refrigerators of other structures. (Embodiment 14) Fig. 31 is an enlarged view of a main part of a refrigerator according to Embodiment 14 of the present invention. The other basic structure is the same as that of the first embodiment or the ninth embodiment. The vacuum insulation material 34 is arranged in connection with the outer case 12, and the film-sealed area of the vacuum insulation material 34 is not provided in the direction in which the polyurethane foam material 13 flows. In other words, the vacuum insulation material 34 is a sealing area of the film of the vacuum insulation material 34 in a state where the polyurethane foam material 13 is not flowing in, and 15 is disposed between the outer case 12 and the inner case 11. With the above structure, the vacuum heat insulating material 34 can stably flow without hindering the flow of the polyurethane foam material 13. Moreover, the polyurethane foam material 13 when injected between the outer box 12 and the inner box 11 is in a high-humidity state. Since it is not directly connected to the sealed area of the film, it is not subjected to thermal stress and can prevent vacuum The heat insulator 34 is deteriorated. 20 Furthermore, the number of sealed areas is reduced, and the vacuum insulation material 34 maintains high gas barrier properties. (Embodiment 15) Figure 32 is a sectional view of a main part of a refrigerator according to Embodiment 15 of the present invention. The other basic structure is the same as that of the ninth embodiment. 35 200300343 The vacuum insulation material 34A can be preferentially arranged from the place where there is debris in the defrosting water pipe in or wiring (not shown). That is, the present embodiment is arranged between the outer box 12 and the inner box η in a place where foreign matter (defrosting water pipe 72 or wiring, etc.) that may hinder the flow of the rigid polyurethane foam material 3 is likely to be blocked. Set the vacuum insulation 5 heat material 34A. By doing so, the heat absorption load of the refrigerator caused by the vacuum insulation material 34A is effectively suppressed, and the energy saving effect is improved. In addition, since the vacuum heat insulating material 34A is provided in a place where there is a possibility that the polyurethane foam material 13 may interfere with the fluidity, heat resistance performance can be secured.

In addition, when the defrosting water pipe 112 is provided, it is preferable to be provided between the vacuum heat insulating material 34A 10 and the outer case 12. Because of this, the defrosting water is insulated by the vacuum insulation material 34A to prevent the defrosting from freezing under the influence of the temperature in the freezer 18, 19, and 19. (Embodiment 16) Figure 33 is a sectional view of a main part of a refrigerator according to a sixteenth embodiment of the present invention. The other basic structure is the same as that of the first embodiment or the ninth embodiment. In this embodiment, the protective member 113 that protects the end face of the outer case 12 and the positioning member when the vacuum heat insulating material 34 is attached are used together. That is, the positioning of the vacuum heat insulating material 34 is performed using the protective member 113 provided on the end surface of the outer box 12 like the end surface of the true heat insulating material 34. In this way, the retaining structure 20 and the vacuum heat insulating material 34 for the end face of the outer case 12 are shared. This prevents the group from wearing the Japanese-style vacuum insulation material 34 from being damaged. In addition, the positioning of the vacuum insulation material 34 when attached is easy and can improve workability. < The protection member 113 may be provided on the top plate to protect the end face of the vacuum heat insulating material u, and it may be used as a positioning member during assembly. 200300343 (Embodiment 17) Fig. 34 is a structural diagram of a vacuum insulation material suitable for a refrigerator according to Embodiment 17 of the present invention. The core material 121 is different from the core material 92 of the tenth embodiment and is composed of a plate-shaped formed inorganic fiber aggregate. The 5 constituent materials of the inorganic fiber assembly are not particularly limited, and glass fiber, ceramic fiber, asbestos, etc., and inorganic fibers, etc., are formed into a plate-like shape from an organic or inorganic bonding material. The gas barrier film 122 is formed in a bag shape at the sealing portion 123. The gas barrier film 122 keeps the inside airtight. There is no particular limitation on the material composition. For example, the vapor-bonding layer film 93 and the metal foil 10-layer film 97 in the tenth embodiment can be constructed in the same manner. That is, one side is a polyethylene terephthalate & L ethylene glycol ester resin in the outermost layer, a foil in the middle layer, and a laminated plastic film made of a high-density polyethylene resin in the innermost layer. On the other hand, for example, the outermost layer is polyethylene terephthalate resin, the middle layer is an ethylene copolymer resin having an aluminum bond layer, and the innermost layer is made of high-density polyethylene resin 15 Made of laminated plastic film. As a method for manufacturing a vacuum insulation material, a gas barrier film 122 made into a bag shape is inserted into a core material, and the inside is evacuated, and the opening is sealed with a welding pad 124 to maintain the inside vacuum. 35 and 36 are a side cross-sectional view and a front cross-sectional view of a refrigerator according to this embodiment, respectively. The basic structure is the same as that of the ninth embodiment, but in Fig. 36, the vacuum heat insulating material 34 disposed inside the side case is extended to the refrigerated area. Further, instead of the vacuum heat insulating material 34A provided on the outer side of the side inner box, a vacuum heat insulating material 34B provided on the side lower inner box η connected to the freezing compartment 9A corresponding to the heat insulating box 10A is provided. In addition, the vacuum heat insulating material 34 and the vacuum heat insulating material 37 200300343 34B are arranged so that the opposed end surfaces are located near the upper end surface of the machine room 20. The lower end of the vacuum heat insulator 34 is located below the upper end of the vacuum heat insulator 34B. Even with such a configuration, similar to the ninth embodiment, the heat-insulating effect on the side can be exhibited. That is, the position where the lower end of the vacuum heat insulating material 34 overlaps with the upper end of the vacuum heat insulating material arranged on the outer side of the inner box on the side 5 cannot be limited. The vacuum heat insulators 34 and 34B are installed in the heat insulation section between the machine room 20 accommodating the compressor 21 and the interior of the storehouse. The inside of the storehouse is a cold well room of minus 20 degrees Celsius D. The machine room 20 is 40 ~ 50 degrees Celsius. That is, the vacuum insulation materials 34 and 34B are effectively 10-thick wall portions in the machinery room 20 and the freezing room 19 with relatively large insulation temperature differences. In addition, the rigid polyurethane foam material 13 is injected into the thermal insulation box 10A. Generally, the front opening of the thermal insulation box IOA is generally arranged below. Further, a stock solution of the polyurethane foam material 13 is injected from a polyurethane injection port provided at two places at approximately the center in the height direction of the back surface of the heat insulation box 10A. In this way, the flow of the foamed polyurethane hair 15 and the material 13 is to expand the polyurethane injection port in the two places described above as a central fan-shaped expansion. The final arrival point of the polyurethane foam material 13 is the top surface and bottom surface of the thermal insulation box 10A, and the surface of the machine room 20. In this embodiment, a real 20-air insulation material 36 having a high flatness is disposed on the surface of the machine room 20 constituting the polyurethane foam material 7 and the material 13 finally arrives at the place. Therefore, the size of the space near the place where the polyurethane foam material 13 finally arrives can be surely ensured, the filling property of the polyurethane foam material 13 can be improved, and a certain thermal insulation performance can be ensured. Since the thermal insulation wall thickness with respect to the thermal insulation box 10A or the coverage ratio of the outer surface of the refrigerator 10 is the same as that of the embodiment, the description is omitted. 38 200300343 40 Vacuum insulation materials 32, 33, 34, 34B, 35, 36, 37, 38, 39, and 41 are as described above, and the core material 121 is formed by a flat plate of the bonding material fiber assembly with gas barrier properties. The film 122 is covered, and the interior is pure and empty.

5 10A. Moreover, it is the same as the polyurethane foam material l3-constituting a thermal insulation ㈣ 10A. The vacuum insulation material shown in Fig. 34 may be applied to other embodiments. ίο 15 20 Furthermore, the vacuum insulation materials 34B, 35, and 36 are connected in advance along the core material 121 to the surface shape of the inner box 11 to form the composite material. * In such a formation, there will be no voids on the contact surfaces between the inner box 11 and the vacuum insulation 34B, 35, 36. Therefore, it is possible to prevent the unevenness and the like of the inner box 11 and to improve the appearance and appearance. In addition, the vacuum insulation materials 32, 33, 34, 34b, 35, 36, 37, 38, 39, 40, and 41 are based on the test method according to the Japanese Industrial Standard JIS-〇22i, and the flexural modulus of elasticity is set to 4 ~ / M is ideal. Bending elasticity is the ratio of the bending stress to the corresponding strain within the limits of the bending ratio. In addition, since the bending elastic modulus of the polyurethane swimming plastic 13 is about _meter, the bending elastic modulus of the vacuum heat insulating material is preferably 8 times as large. ;, I will use the strong insulation type I »of real money hot materials with different bending elasticity. The result table is the first table. As a test method, when a food load of about 0 kg was added to the door of the refrigerator compartment, the horizontal position of the uppermost part of the side surface of the thermal insulation box body was measured. Table 1 ^ ^ Insulation box specifications 尽 A sample B sample C rigid polyurethane only 1 vacuum insulation + rigid polyurethane insulation + rigid polyurethane '— 39 200300343 foam material formate Bending elasticity of foam material formic foam material vacuum insulation material — 20 Pa / m 40 Pa / m The side of the thermal insulation box is curved 3 mm 4 mm 3 mm. From the above results, the thermal insulation box 10A When the rigid polyurethane foam is laminated with a vacuum insulation material having a bending elasticity of about 40 Pa / m, it becomes 5 times as hard as the rigid polyurethane foam (A). The strength is equal to or less than. This is because the thermal insulation wall is changed from a single structure to a multi-layer structure, and the bending strength is low. In addition, the use of a vacuum insulation material having a flexural modulus of 40 Pa / m or more results in a multi-layered structure with only a rigid polyurethane foam material having a strength higher than that of the rigid polyurethane foam material. Since the flexural modulus of rigid polyurethane foam is 8 Pa / m, the flexural modulus of vacuum insulation material is 10 times the rigid polyurethane foam. The structure of the heat-insulating box has the same strength or higher. In order to increase the bending strength of the vacuum heat insulating material, it is possible to select or increase the amount of the binder material used in the plate-like forming of the inorganic fiber assembly of the core material 121, and the like. These costs are high at the time of manufacture. Therefore, the bending elasticity of the vacuum insulation material is about 64 Pa / m, which is the upper limit of cost performance. In other words, since the bending elastic modulus of the vacuum insulation material is 5 times or more and 8 times or less of the rigid polyurethane foam material, the strength of the heat insulation box of the multilayer structure can be made while satisfying the cost performance. Equivalent or more. The vacuum heat-insulating material having such a bending strength is as described above. The core material 121 20 is manufactured by covering a flat plate-shaped formed inorganic fiber assembly with a gas-barrier film 122 and evacuating the interior. Compared with the vacuum insulation material with only inorganic fiber collection 40 200300343 moon bean as the heartwood, the inorganic fiber assembly is bonded and formed by the bonding material to improve the compressive strength, bending strength and flatness of the vacuum insulation material. Therefore, when such a vacuum insulation material is used, the strength of the insulation box 10A can be increased. It is also incorporated into the heat-insulating box 10A to maintain a high level of 5 degrees, which can ensure the size of the flowing space portion of the polyurethane sieve plastic 13 formed inside the heat-insulating box 10A. Thereby, the polyurethane foam is improved; the fluidity when the plastic 13 is not injected, the filling rate of the polyurethane foam 13 is improved, and a certain thermal insulation performance is obtained. Furthermore, since the flatness of the heat-insulating materials 32, 33, 34, 34B, 35, 36, 37, 10 38, 39, 4G, and 41 is increased, the space portion of the surface directly contacted by the adhesive can be excluded. As a result, the adhesion to the adhesive surface is increased, and it is possible to prevent the vacuum insulation material from falling off and falling during manufacture and assembly, to improve the reliability and workability. In addition, as the flatness of such a vacuum insulation material is increased, the flatness of the thermal insulation box 10A directly contacting the surface is also increased, and the appearance of the refrigerator 15 is improved. In addition, since the strength of the moxibustion vacuum insulation material is increased, it is easy to take out the vacuum insulation material when the refrigerator is discarded or disassembled after use, and the recyclability is improved. In addition, when the vacuum insulation materials 32, 33, 34, 34B, 35, 36, 37, 38, 39, 40, 41 are adhered and fixed to the inner box η or the outer box Π or Wei outer plate, the bonding roller Ideal for coating on adhesive surfaces. As the adhesive, for example, a hot melt made of a rubber-based material is used. The adhesion strength test of the vacuum insulation material and the outer case 12 when the adhesive coating specification is changed is shown in Table 2 of the prefecture table. As a test material to supplement the Japanese Industrial Code ㈣S-ZG23k8, in this experiment _ test with a set width condition 20 200300343 Examine the board to find 180 degrees peeling adhesion. Table 2 Sample D Sample E Adhesive Coating Specifications 180 Degree Peeling Adhesive Force Full Coverage Straight 10 mm wide (adhesion area ratio 40%) (Newton / 25 mm wide) 30 Newton 16 Newton 5 In addition, adhesive The agent system is a rubber-based hot melt, and the test substrate is a stainless steel laminated polyethylene terephthalate. The coating thickness of the adhesive is 2 kg when the pressure is 30 μm, and the roller 1 is reciprocated. The test ambient temperature was 23 degrees Celsius. According to the results in Table 2, when the adhesive was applied on a straight line at regular intervals at a regular interval compared with the method generally implemented in Sample E, the adhesion strength was increased by two times due to the full coating. Because of this, the vacuum insulation materials 32, 33, 34, 34B, 35, 36, 37, 38, 39, 40, and 41 do not fall off or fall during the manufacturing steps. In addition, since the vacuum heat insulating materials are strongly bonded and fixed to the inner box 11 or the outer box 12, 15 the strength of the heat insulating box 10A is increased. In addition, since the adhesive is completely coated, no space is generated on the bonding surfaces of the vacuum insulation materials and the inner box 11 or the outer box 12, and no unevenness is generated in the heat insulation box 10A of the refrigerator 10, which can improve the appearance of the decent. Furthermore, the vacuum insulation materials 32, 33, 34, 38, 39, 40, 41 are connected to the outer case 12 and arranged. In this way, the box 12 is provided with a true high-level empty heat insulating material outside the forming plane. Since there is an adhesive on the contact surface, no gap will be generated on the contact surface between the outer box 12 and the vacuum insulation material. Accordingly, the outer box 12 can be prevented from being uneven, and the appearance can be improved. 42 200300343 Also, because the vacuum insulation materials 34B, 35, and 36 are connected to each other, ^ suppresses the foaming agent of the polyurethane foam material 13 located on the side of the outer box 12 to finish the heat insulation of the insulation wall. Thermal insulation performance. Furthermore, the vacuum insulation materials 33, 35, 34, 34B, and 36 are installed inside the heat insulation wall corresponding to the cold and east temperature zones. This can effectively improve the thermal insulation performance of the thermal insulation box corresponding to the cold temperature zone with a large difference from the Bingxiao outer shirt. In addition, after ensuring the flow space of the polyurethane foam material 13 in the thermal insulation wall portion with a large temperature difference in the thermal insulation box 10A, the maximum thickness of the vacuum and thermal insulation material is ensured, but the thermal insulation box 1 The inner volume of 〇Α, φ Tinan is the most important for adiabatic performance. In this embodiment, since the core material ι2ι is composed of a flat plate-shaped formed inorganic fiber aggregate, the vacuum heat insulating materials 33, 35, 34, 34B, and 36 have high flatness. Therefore, after the cold beam with a large temperature difference reaches 18A and 19, the% hot wall portion 'ensures the size of the flowing space of the polyurethane foam 13, and can maximize the sales of real-line hot materials M,%, · Thickness of 34, 34B, 36. Therefore, a refrigerator with high heat insulation performance can be provided. The vacuum heat insulating materials 38, 39, 40, and 41 are arranged on the side of the heat insulating wall inside the door panels 27, 28, 29, and 30 constituting the openings provided in the front of the refrigerator. In this way, since the outer panels of each of the lintels 27, 28, 29, and 30 are formed, the high-flatness vacuum insulation materials 38, 39, 40, and 41 are arranged, and the contact surfaces of the coffee outer plates and the vacuum insulation materials No voids will occur. Therefore, it is possible to prevent the unevenness of the outer case 12 and the like to improve the appearance and the appearance. In the present embodiment, as the hydrocarbon of the polyurethane-foaming material 13 foaming agent, for example, cyclopentane is used. Therefore, compared with the conventional fluorite carbide (fl⑽) foaming agent, it protects the global environment and prevents warming. Also, Yu Zhen 43 200300343 is composed of a non-combustible inorganic fiber assembly, and even if a combustible hydrocarbon-based foaming agent is used, the safety is high. In addition, the decrease in thermal insulation performance due to the application of a hydrocarbon-based foaming agent can be supplemented by the high thermal insulation performance of a vacuum insulation material, thereby improving the thermal insulation performance of the thermal insulation box. 5 Furthermore, in the present embodiment, as the refrigerant in the cold-bundle cycle composed of the compressor 21, the condenser 26, the refrigerating cooler 22, and the refrigerating cooler 24, a flammable natural refrigerant hydrocarbon is used. Ding burn. Therefore, compared with the conventional fluorocarbon-based refrigerant, it is related to the environmental protection of the earth. Prevent warming. In addition, since the vacuum heat insulating material is composed of a non-combustible inorganic fiber assembly 10, the safety is high even if a hydrocarbon which is a flammable refrigerant is used. In addition, in the refrigerator of this embodiment, the vacuum insulation material is fixed to the inner box 11 or the outer box 12 or the outer panels of each door case, and it is explained that the polyurethane foam material 13 does not foam in the space portion. However, as in the embodiment 丨, the space portion of the vacuum insulation material is arranged in the middle of the inner box 丨 丨 or the outer box 12, and the polyurethane foam material 13 may be foamed. In this case, the core material i2i of the vacuum insulation material is composed of a plate-shaped formed inorganic fiber assembly, and the vacuum insulation material has a high flatness. Therefore, the dimensions of the space portion of the inner box u or the outer box 12 and the vacuum insulation material can be ensured with high accuracy, and the polyurethane foam 20 can be reliably filled. In addition, since the inner case or the outer case? Is not directly contacted, the appearance of the heat insulating case 10A is not impaired. In addition, because the vacuum insulation material is arranged in the middle of the inner box 11 or the outer box 12, the surrounding is made of polyurethane_foam_13, and it becomes unnecessary to fix the vacuum insulation material with an adhesive or the like. 121 It is possible to dispose the joint material in advance [child-shaped vacuum insulation 44 200300343] The hot material may be arranged at the corners of the top and side surfaces of the refrigerator 10. In this case, the coverage of the vacuum insulation material to the thermal insulation box 10A can be further improved. Further, since a vacuum heat insulating material having a high bending strength is disposed at a corner portion of the heat insulation box 10A, the strength of the heat insulation box 10A can be effectively improved. · 5 Furthermore, in this embodiment, it has been described that the vacuum insulation materials 38 '39, 40, and 41 provided in the door openings 27, 28, 29, and 30 arranged on the front of the refrigerator 10 are connected to the door outer panels. . However, as in the embodiment 丨, the vacuum insulation materials 38, 39, 40, and 41 may be arranged in the middle portion of the inner box and the outer plate of each door, and the polyurethane foam material 13 may be filled in the space portion. In this case, due to the high flatness of the vacuum insulation materials 38, 39, 40, and 41, the size of the space portion capable of filling the polyurethane foam material 13 can be reliably ensured, and the polyurethane can be reliably filled. Urethane S purpose foaming material. Furthermore, since the outer panel is not directly connected to the vacuum insulation materials 38, 39, 40, and 41, the surface change of the outer panel of each lintel can be further suppressed. 15 (Embodiment 18) A refrigeration cycle diagram of a refrigerator according to Embodiment 18 of the present invention is shown in Fig. 37. The other structure is the same as that of the first embodiment. The following uses Figure 37 and _ Figure 2 to explain. The refrigerant discharge port 138A of the compressor 138 is connected to the inlet of the two-way switching valve 140 of the flow path switching path through the condenser 139. One switching port mo of the switching valve mo is an inlet connected to a freezer evaporator (hereinafter, vaporized state) 136 through a freezing capillary 141. The outlet of the hairpin 136 is connected to the inlet of the check valve 143 through a reservoir 142. The outlet of the check valve 143 is connected to the refrigerant inlet 138B of the compressor 138. The other outlet of the switching valve 140 is connected to the inlet of the evaporator (hereinafter, evaporator) 134 for the refrigerating compartment through the refrigerating capillary 45 200300343 and the officer 144. The outlet of the evaporator 134 is connected to the outlet of the check valve 143. That is, facing the compressor 138, the evaporator 134 and the evaporator 136 are connected in parallel, and the outlet of the evaporator 136 is connected to the outlet of the evaporator 134 through the check valve 143. -5 The outline of the above structure and its effects are shown below. First, when the compressor 138 is driven, the refrigerant discharged from the compressor 138 flows to the refrigerating chamber evaporator 134 to switch the refrigerant flow path by the switching valve 14o. That is, a state shown by a dotted arrow symbol 15 in FIG. 37 is created. This state is hereinafter referred to as a refrigerator mode. In the refrigerating mode, the refrigerant discharged from the compressor 138 performs a well-known 10 state change, and then the evaporator 134 and the air around the evaporator 134 are sent out. The evaporator 134 in FIG. 37 corresponds to the cooler 22 in FIG. 2. At this time, the air cooled by the evaporator 134 is sent to the refrigerating compartment 15 and the vegetable compartment 16 by the air blowing action of the refrigerating blower 23 to cool the refrigerating compartment 15 and the vegetable compartment 16. Furthermore, when the compressor is driven, the refrigerant discharged from the compressor and 15 I38 by the switching valve 14 flows to the evaporator 136 to switch the refrigerant flow path. That is, the state shown by the raised arrow symbol 151 in Fig. 37 is created. This state is hereinafter referred to as a freeze mode. In the freezing mode, the refrigerant discharged from the compressor 138 is executed. After the well-known state changes, it is sent to the evaporator 136 to cool the surrounding air of the evaporator 136. The evaporator 136 in Fig. 37 is equivalent to the cooler-20 in Fig. 24. At this time, the air of the cooler cooled by the evaporator 136 is sent to the switching room 17, the ice-making room 18, and the freezing room 19 by the air supply function of the cold air. By doing this, the refrigerating temperature zone space formed by the refrigerating compartment 15 and the vegetable compartment 16 and the temperature zone space formed by the cutting age 17, the ice-making compartment 18, and the cold; the east compartment 19 are independently cooled. Therefore, maintaining the cooling temperature of the evaporator ㈣: 46 200300343 degrees minus 5 degrees Celsius, and the evaporator 16 is about -40 degrees Celsius below zero degrees Celsius, effectively providing the temperature in the storehouse suitable for each cooling space. Therefore, this effect is improved. In addition, the refrigerating temperature zone space and the freezing temperature zone space are independently cooled for time division, and the amount of heat that must be removed is reduced. Therefore, the heat radiation # of the condenser 139 also becomes small. As a result, the piping valley of the entire cold-ring circuit is reduced to some extent. Therefore, it is possible to suppress to a certain extent the risk of fire when the refrigerant leaks when using a flammable slave hydrogen-based natural refrigerant as the refrigerant. Further, when the compressor 18 is stopped in a state where both the refrigerating temperature zone space and the freezing temperature zone space are cooled to a preset temperature of 10, the compressor 138 is stopped in a refrigerating mode. In the refrigerating mode, the inlet of the refrigerant outlet 138A of the compressor 138 and the inlet of the evaporator 134 are communicated by the action of the switching valve 140. The refrigerant outlet 138A and the inlet of the evaporator 136 are blocked. If the compressor 138 is stopped in this state, the high-temperature side 15 represented by the condenser 139 will not allow the high temperature refrigerant to flow into the evaporator 136. In addition, due to the function of the check valve 143, no refrigerant flows back from the evaporator 134 toward the evaporator 136. Therefore, the refrigerant can be kept at a low temperature in the evaporator 136, and an unnecessary increase in the temperature of the evaporator 136 can be prevented. As a result, the energy loss of the refrigeration cycle is further reduced, and the energy saving effect is further improved. · 20 In addition, the conventional refrigerator is generally R134a used as a refrigerant. On the other hand, in the refrigerator of this embodiment, as in Embodiment 17, r 6003 isobutane can be used as a hydrocarbon-based natural refrigerant. Due to the structure as described above, compared with a case where the refrigerator 10 is insulated from the door panels 27, 28, 29, 30, and 31 only with the rigid polyurethane foam material 13, 47 200300343 greatly reduces the heat absorption amount of the entire refrigerator. As a result, the energy-saving effect due to the reduction in the amount of heat absorbed by the cabinet can be obtained. In addition, due to the parallel switching system, even when the cooling and refrigerating temperature zone spaces and the freezing temperature zone space are mutually cooled, the temporal temperature fluctuation range in the stop side storage becomes small. In other words, due to the parallel switching system, the cooling efficiency is improved, the energy saving effect is improved, and at the same time, the insurance of food is also improved. In addition, because the heat absorption of the box is reduced due to the use of a vacuum insulation material, compared with the case where the box is only insulated with a rigid polyurethane foam material, the amount of heat that needs to be removed and the amount of heat to be dissipated is reduced. . Therefore, the volume of the piping 10 becomes small. In addition, according to the conventional heat-insulating box of rigid polyurethane foam material, for the purpose of preventing condensation on the surface of the refrigerator, a part of the heat-dissipating pipe (not shown) constituting the condenser 139 is buried in the rigid polyamine. Carbamate foam. In this embodiment, since a vacuum heat insulating material is used in a part where there is a possibility of dew condensation, a heat-dissipating pipe designed for dew condensation prevention is also unnecessary. 15 Therefore, the piping capacity has been significantly reduced as a whole. As a result, the amount of refrigerant necessary for cooling is significantly reduced. When a natural refrigerant with a flammable hydrocarbon system is used, even if the refrigerant leaks, the risk of fire is very low. In addition, even if the compressor 138 has a fixed number of rotations, the above-mentioned effects are obtained, but it is preferable to use a variable number of rotations of the compressor 138 to form a 20 refrigeration cycle. With this configuration, the difference between the maximum heat absorption load when the door is opened and closed and the food load in the warehouse caused by the use of the vacuum insulation material can be controlled by the number of rotations of the compressor. For a compressor with a certain number of revolutions, it is necessary to ensure an excessively large cylinder volume in conjunction with the maximum load, and the time to stop the compressor at an increased time will increase the time variation of the 200300343 temperature in the warehouse. On the other hand, the use of a variable-speed compressor can reduce the loss of such energy-saving effects, and can suppress the time fluctuation of the temperature in the storage. In addition, since the cylinder volume becomes smaller, a smaller amount of refrigerant can be designed. Therefore, even if the hydrocarbon-based refrigerant of the flammable refrigerant leaks out of the cooling system, the danger of the flammable refrigerant becomes very small. The design of the coverage of the vacuum heat insulating material or the thickness of the heat insulating wall of the refrigerator is the same as that of other embodiments, so the description is omitted. Figure 38 shows the structure of the vacuum insulation material. The basic structure is the same as that of the tenth embodiment. In Fig. 38, the core material 145 is composed of an inorganic fiber aggregate 145 such as glass wool. The vacuum insulation material is formed by inserting a core material 145 into a cover material other than the metal foil layer film M6A and the steam layer film 146B, and vacuum-sealing the opening portion inside. Since the material of the core material 145 or the films 146A and 146B, the thermal conductivity, and the like are the same as those of the tenth embodiment, the description thereof is omitted. 15 With such a structure, a vacuum insulation material having approximately 10 times the heat insulation performance can be obtained compared to a rigid polyurethane foam material. Therefore, the effect of reducing the heat absorption of the cabinet when using a vacuum insulation material is greatly increased. As a result, the energy saving effect is greatly improved, and even when a parallel switching system is used, the temperature fluctuation range in the warehouse is reduced in time, and the food freshness is improved. Furthermore, since the amount of heat absorbed is further reduced by 20, the amount of necessary refrigerant can be suppressed to be small, and even if isobutane, which is flammable, is used as a refrigerant, the risk of leakage of the refrigerant is further reduced. In addition, the inorganic fiber assembly used in the core material 145 is flame-resistant, and in case of fire in the refrigerator, the safety is higher than that made of a rigid polyurethane foam only. 49 200300343 Figure 39 is a schematic diagram of a vacuum insulation material. The thickness of the vacuum insulation material i49 was 15 mm. That is, a vacuum heat insulating material is provided so that the surface formed by the two sides 147 and 148 faces the direction in which the heat must pass through and the vertical direction is formed. Here, the length of the sides 147 and 148 is preferably 200 mm or more. 5 By doing so, the following effects can be obtained. Since the gas-barrier films 146A and 146B forming the outer material of the vacuum insulation material have metal film layers, a so-called thermal bridging phenomenon is generated by heat transfer. Therefore, if the lengths of the edges 147 and 148 of the area formed by the vacuum insulation material are too small, the original heat insulation performance of the vacuum insulation material cannot be derived, and the insulation effect is reduced compared to the amount of the vacuum insulation material used. On the other hand, since the edges 147 and 148 are 200 mm or more ', the original thermal insulation performance of the vacuum insulation material can be extracted. That is, it can be confirmed experimentally that the heat leakage can be suppressed by the thermal bridge. From the above, since the length of both sides in the thickness direction of the three sides constituting the vacuum insulation material is 200 mm or more, the original thermal insulation performance of the vacuum insulation material can be derived. As a result, it is possible to effectively reduce the heat absorption amount of the entire refrigerator by using the vacuum heat insulating material in a state of high cost performance. As a result, in the above-mentioned embodiment, the energy-saving effect can be further enhanced, and the effect of reducing the temperature fluctuation in the warehouse over time can improve the effect of keeping food fresh and the effect of reducing the risk of leakage of natural refrigerant due to less refrigerant. 20 In addition, although the thickness 149 of the vacuum insulation material is 15 mm, if it is in the range of 5 to 20 mm, there is no possibility that the foaming filling property of the polyurethane foam material 13 may be hindered. Select appropriate insulation performance. In this embodiment, the structure of the refrigerating cycle and the dimensions of the vacuum heat insulating material are the same as those of the first embodiment. Moreover, such a structure is effective even if it is applied to 50 200300343 other embodiments. Although the embodiments of the present invention have been described above, even in any of the embodiments, they can be used in refrigerators with superior appearance, heat resistance, and heat resistance. In addition, the structure peculiar to each embodiment can be combined with the implementation of other embodiments, and such a combination system is within the scope of the present invention.
