As shown in Fig. 2, the shell 2 of the refrigerator 1 is by being formed with the outer container 9 of opening portion 8 in front surface and to be accommodated in this outer Interior case 10 in case 9 is constituted.The outer container 9 is formed by steel plate, and interior case 10 is formed by resin materials such as plastics.

Vacuum insulation panel and tube parts are equipped between above-mentioned outer container 9 and interior case 10.

In addition, between outer container 9 and interior case 10, and in the part of not vacuum insulation panel, it is filled with foam heat insulating material.

Specifically, as vacuum insulation panel, top plate 11 is arranged in ceiling portion, in side between outer container 9 and interior case 10 Face distribution sets side panel 12.In the following, for convenience, the lateral parts in the left side of shell 2 will be disposed among side panel 12 Panel be referred to as Left-Hand Panel 12A, the panel for the lateral parts for being disposed in the right side of shell 2 is referred to as right panel 12B.

It is well known that the bag portion part as exterior film is filled in for example, the core materials such as glass fibre are laminated, it is right The inside of the bag portion part vacuumizes and then sealed opening, thus forms the vacuum insulation panel.In addition, though being omitted Still vacuum insulation panel also is arranged in the bottom parts and back portion of shell 2 in diagram.

In addition, as tube parts, lateral tube 13 is arranged in lateral parts, in opening portion between outer container 9 and interior case 10 Anti-condensation pipe 14 is arranged in 8 periphery, and anti-condensation pipe 14 is to extend to another via ceiling portion from a side of shell 2 Side.Also that is, anti-condensation pipe 14 is at least consecutively provided in the top of opening portion 8 and each side of left and right.These tube parts are: For the pipe that the refrigerant of the midway from compressor (not shown) to cooler passes through, be in order to prevent 1 surface sweating of refrigerator and set It sets.

Although in addition, impart title respectively to simplify the explanation and by lateral tube 13 and anti-condensation pipe 14 herein, this A little pipes play same function as so-called heat-dissipating pipe.

In addition, the arranging mode of vacuum insulation panel shown in Fig. 2 and tube parts is an example, not only It is defined in this.

Then, it explains the role of the above composition.

Firstly, illustrating a part of the manufacturing process of shell 2.As shown in figure 3, by formed outer container 9 ceiling top plate 9a, The left plate 9b and right side plate 9c for forming the side of outer container 9 are linked up, and are carried out to the thin plate steel plate for the state that links up Molding, thus come manufacture constitute shell 2 outer container 9.

Specifically, for thin plate steel plate using cold roll forming machine etc., by bending section made of bending side plate, at End for 2 front-surface side of shell forms out flange part 9d.Flange part 9d forms the periphery of opening portion 8, such as Fig. 2 and back Shown in described Fig. 3, anti-condensation pipe 14 is arranged in the inner surface side of flange part 9d.In addition, in the end for becoming 2 back side of shell Form out flange part 9e.

Then, there are the face of that side of flange part 9d that is, the inner surface of outer container 9 in the formation of thin plate steel plate, utilize aluminium foil Adhesive tape etc. and lateral tube 13 is individually fixed in left plate 9b and right side plate 9c.By pressure, the bonding such as hot melt adhesive will be coated with The side panel 12 of agent 15 (referring to Fig. 6) is fixed on the face for pasting side.

Moreover, by the crest line between the crest line and top plate 9a and right side plate 9c between top plate 9a and left plate 9b to apply It is bent in a manner of 90 degree of folding lines, it is and interior as shown in figure 4, at flange part 9d to form the outer profile of substantially U-shaped Case 10 is fitted into, and at flange part 9e, is carried out with backboard 9f chimeric.Accordingly, outer container 9 is integrated with interior case 10, shape At the substantially outer profile of shell 2.In addition, though the illustration is omitted, still, bottom plate is also installed at this moment.

In addition, since anti-condensation pipe 14 is the periphery for being disposed in opening portion 8, so, if it is simple consider if, can also be with It is the stage before thin plate steel plate is formed as U-shaped, for example, the stage after thin plate steel plate forms out flange part 9d, It is disposed on thin plate steel plate again.But as noted previously, as thin plate steel plate is bent into 90 degree, therefore, once in advance with setting up defences If dew tube 14, when being molded into U-shaped, it is possible to the situation for the cracking of anti-condensation pipe 14 occur or being crushed.

Alternatively, it is also contemplated that anti-condensation pipe 14 is fixed on interior 10 side of case, then combined with outer container 9.But by In being possible to, dislocation occurs for anti-condensation pipe 14 when chimeric with flange part 9d and anti-condensation pipe 14 is configured in close to storage The position of room and cause thermal energy to flow into refrigerator to increasing by 1 power consumption of refrigerator, therefore not preferably.

As a result, as described above, in the case where thin plate steel plate bending is formed the manufacturing process of outer container 9, need inciting somebody to action Anti-condensation pipe 14 is arranged after thin plate steel plate bending again.In this case, it is desirable to for the operation of anti-condensation pipe 14 to be arranged Space, so, the previous vacuum insulation panel shown in Fig. 4 as comparative example (in the following, be simply termed as previous plate for convenience 112) it in the case where not significantly alterring manufacturing process, needs to have left from the anti-condensation pipe 14 for being disposed in the side flange part 9d It is arranged in the state of distance necessary to operation (D).

Stated differently, since the insulative properties of general vacuum insulation panel are better than the insulative properties of foam heat insulating material, therefore And, it is desirable to be able to it is disposed in the range as roomy as possible of the lateral parts of shell 2, still, the case where using previous plate 112 Under, in order to carry out pasting the operation of anti-condensation pipe 14, vacuum insulation panel can not be matched to the critical position for being set to the side flange part 9d. The inhibition of storeroom, the space being also greatly improved are flowed into about the raising of heat-proof quality and for thermal energy as a result,.

Therefore, in the present embodiment, as described below, main manufacturing process is not changed, it will be able to by vacuum insulation panel With being set to: by the extremely close position of anti-condensation pipe 14 that is, to greatest extent close to the position of anti-condensation pipe 14.

Fig. 5 is schematically shown: be disposed in it is among the vacuum insulation panel between outer container 9 and interior case 10, in the left side of shell 2 Lateral parts be arranged Left-Hand Panel 12A.But in Fig. 5, subtle portion is highlighted for ease of description and consciously Point, there are the parts different from actual size or size.In addition, though the detailed description omitted, still, right in shell 2 The right panel 12B that the lateral parts of side are arranged is formed are as follows: relative to shell 2 center and with Left-Hand Panel 12A at symmetrical Shape (referring to Fig. 9).

Left-Hand Panel 12A generally connects by leading portion portion 12a, back segment portion 12b and by leading portion portion 12a and back segment portion 12b The return portion 12c come is picked up to constitute.Left-Hand Panel 12A is adapted to: leading portion portion 12a becomes the front side of shell 2, back segment portion 12b becomes the back side of shell 2, and up and down direction is the up and down direction of shell 2 in figure.In addition, in Fig. 5, diagram inboard is 9 side of outer container, side is interior 10 side of case to diagram at the moment.

The thickness (L1) of leading portion portion 12a is configured to the thickness (L2) less than back segment portion 12b.Moreover, leading portion portion 12a with Between back segment portion 12b, that is, the midway on the front-rear direction of shell 2, it is formed with return portion 12c.Wherein, leading portion portion 12a Thickness (L1) is configured to the width of the flange part 9d on the left and right directions less than shell 2.

Return portion 12c is formed as extending along the up and down direction of shell 2, and the thickness (L3) of return portion 12c is configured to small In leading portion portion 12a and back segment portion 12b.By the thickness for the core material for being not filled with core material or being filled be thinner than other positions come The return portion 12c is formed, return portion 12c has flexibility to a certain degree.As core material, the substance of cloth-like can be used, Core components are not configured in return portion 12c, or the number of stacking is fewer.

The width (L4) of return portion 12c is set to be greater than the thickness (L1) of leading portion portion 12a and the thickness of back segment portion 12b It spends (L2).Accordingly, as described later, Left-Hand Panel 12A can be turned back in return portion 12c (referring to Fig. 6).In addition, back segment 9 side of outer container of portion 12b is formed with: 1 or more the receiving portion 12d for accommodating lateral tube 13, is 2 receipts in present embodiment Appearance portion 12d.

It can be sharp by the way that the position after reducing core material stacking number is provided, or after forming vacuum insulation panel Press etc. with mold forming the receiving portion 12d to apply pressure.In addition, among the 12d of receiving portion, near leading portion portion The side 12a, also to become the receiving portion 12d of the side return portion 12c in the side return portion 12c be opening-like.In addition, receiving portion 12d Quantity or position can suitably be selected according to the quantity of lateral tube 13 or position.

Since the return portion 12c of such Left-Hand Panel 12A has flexibility, Left-Hand Panel 12A can turn back It is easily bent in the longitudinal direction at portion 12c.Specifically, bonding agent 15 is not applied in Left-Hand Panel 12A, leading portion portion 12a, In the state that back segment portion 12b applies bonding agent 15, as shown in figure 3, press in placing to thin plate steel plate, as a result, firstly, The back segment portion side 12b is securely adhered on thin plate steel plate.At this point, due to not applying bonding agent 15, leading portion in leading portion portion 12a Portion 12a will not be bonded on thin plate steel plate.

Moreover, before being bent into U-shaped or after being bent into U-shaped, as shown in fig. 6, by leading portion portion 12a into Row bending and be overlapped in back segment portion 12b, be fixed temporarily with adhesive tape 16, as a result, flange part 9d and Left-Hand Panel 12A it Between, tighter say it is between flange part 9d and back segment portion 12b, it can be ensured that biggish working space.

Then, using the biggish working space, as shown in fig. 7, can be in the inner surface side for being formed in flange part 9d Space in, be easy to carry out and accommodated anti-condensation pipe 14 and fixed operation.At this point, due to leading portion portion 12a be by It is fixed temporarily, so operation will not be interfered.

Hereafter, as shown in figure 8, removing adhesive tape 16, close to the front end side ground sticking two-faced adhesive tape band 17 of leading portion portion 12a, before making Section portion 12a is pasted on left plate 9b with being located at the position of the side flange part 9d, and thereby, it is possible to so that Left-Hand Panel 12A maximum limit Left-Hand Panel 12A is arranged close to the state of flange part 9d in degree ground.In this case, it also can be made and be not contacted with flange part 9d State.In addition, right panel 12B is also arranged with same process.

At this point, Left-Hand Panel 12A is adapted to: between the leading portion portion 12a in the state of after arranging and back segment portion 12b away from The width (L4) of return portion 12c in the state of being shorter than after shaping from (L5).Also that is, Left-Hand Panel 12A is formed are as follows: when forming Length on front-rear direction is more than the degree of flange part 9d, moreover, being also formed as: leading portion portion 12a and back segment portion 12b are added up to Length after coming is not up to the degree of flange part 9d.

Moreover, the width of return portion 12c is relatively small in the state that Left-Hand Panel 12A has been arranged, as a result, not by Fill core material or because core material is also thinner than other positions and the return portion 12c of heat-proof quality relative reduction shared by gap Also just become smaller.At this point, return portion 12c is disposed of: bag portion part accumulates the state of fold out.

Then, after the installation for terminating backboard 9f and bottom plate, as shown in figure 9, in shell 2, for example, being carried on the back from setting Inlet 18 on plate 9f injects liquid foam heat insulating material like that as shown by arrow H.At this point, being in weight in flange part 9d In the state of below power direction, inject foam heat insulating material, foam heat insulating material on one side blister that is, foam heat insulating material while, Filling is gone down upward on one side for expansion.

As a result, in the region (R) of the relatively thin side flange part 9d of the thickness of leading portion portion 12a, because of water before inflation Square upwards than broader, it is possible to improve fillibility.In addition, due to the front end of Left-Hand Panel 12A and right panel 12B Side is fixed by double faced adhesive tape 17, accordingly it is possible to prevent: when foam heat insulating material after the implantation starts blistering, left side The phenomenon that plate 12A and right panel 12B are detached from.

Embodiment from the description above can obtain following such effect.

In the refrigerator 1 of embodiment, the anti-condensation pipe 14 as tube parts is matched between outer container 9 and interior case 10 It is located at the periphery of 8 side of opening portion, the side panel 12 as vacuum insulation panel is formed with: not being filled core material or is filled The thickness of core material be thinner than the return portion 12c at other positions, moreover, being also formed on the front-rear direction of shell 2: comparing return portion Position that is, leading portion portion 12a of the 12c close to front side, wherein leading portion portion 12a can be folded to than return portion 12c close to rear side Position that is, back segment portion 12b.

Accordingly, due to can easily bend vacuum insulation panel in return portion 12c, thus it is possible to ensure to match It is located at the working space of the anti-condensation pipe 14 of the periphery of opening portion 8, it can also enough by leading portion portion 12a as close to anti-caking Dew 14 side of pipe it is arranged.In addition, back segment portion 12b due to can by pressure be fixed, can connect securely Knot.So not having to change main manufacturing process, it will be able to by vacuum insulation panel close to anti-condensation pipe 14.

In addition, return portion 12c is formed in refrigerator 1 are as follows: the width (L4) for the front-rear direction of shell 2 is big In the thickness of leading portion portion 12a and back segment portion 12b.Accordingly, the 180 degree that leading portion portion 12a can substantially be turned back is to the back segment portion side 12b And be fixed, can not only ensure to turn back required flexibility, additionally it is possible to be easy to carry out and be fixed temporarily.

In addition, vacuum insulation panel is adapted in refrigerator 1: leading portion portion 12a and back segment portion in the state of after arranging The distance between 12b (L5) is shorter than the width (L4) of return portion when shaping.

When pasting leading portion portion 12a in the state of stretching return portion 12c in the longitudinal direction, the thinner part of core material Heat-proof quality will be deteriorated.In addition, if vacuum insulation panel occurs during manufacturing, the width on front-rear direction is inconsistent, position is arranged Dislocation is set, the front end side that will lead to the front end side of vacuum insulation panel that is, leading portion portion 12a is not likely to reach flange part 9d.

Therefore, by being arranged as described above, the return portion 12c with flexibility is made: bag portion part accumulates pleat out The state of wrinkle, it will be able to the inconsistent of size etc. is absorbed, moreover, it is also possible to which reliably covering most needs using vacuum insulation panel It wants near one of heat-insulated position that is, flange part 9d, in addition, between passing through between constriction leading portion portion 12a and back segment portion 12b Gap, it may also be ensured that as heat-proof quality necessary to shell 2.

In addition, the thickness of the leading portion portion 12a of vacuum insulation panel is thinner than the thickness of back segment portion 12b in refrigerator 1.Moreover, In present embodiment, the thickness (L1) of leading portion portion 12a is configured to the width less than flange part 9d.

In the case where being disposed in vacuum insulation panel close near flange part 9d, vacuum insulation panel once interferes foam The filling of heat-barrier material, foam heat-insulating material will be possible to that thermal insulation can not be led to throughout the space for containing anti-condensation pipe 14 It can reduce.Moreover, in shell 2 when the heat-insulated material of filled and process, usually in 8 side of the opening portion of shell 2 towards the state of downside To be filled.

It is relatively thin by the way that the thickness of leading portion portion 12a to be made into as a result, it will be able to ensure for the heat-insulated material of filled and process Space, so as to improve fillibility, moreover, while the space for ensuring filling, additionally it is possible to prevent vacuum insulation panel The thickness situation all thinning in entire side, thus, it is possible to the problem of preventing heat-proof quality from reducing.

In addition, relatively thin by the way that the thickness of leading portion portion 12a to be made into, it will be able to which reduce: it is touched left plate 9b Cut surface front end portion be bent and a possibility that the end of the flange part 9d that is formed, so as to prevent: vacuum every Hot plate occurs damaging and leads to not keep vacuum state that is, the problem of heat-proof quality reduces.In addition, due to refrigerator 1 Front side be position that works is relatively concentrated, therefore, by the way that relatively thin, energy is made in the thickness of leading portion portion 12a The problem of enough preventing works from interfering vacuum insulation panel.

In addition, the leading portion portion 12a of vacuum insulation panel is secured in outer container 9 by double faced adhesive tape 17 in refrigerator 1 Surface, on the other hand, back segment portion 12b is secured at the inner surface of outer container 9 by bonding agent 15.

Although previous general vacuum insulation panel is stuck by bonding agent 15 as hot melt adhesive, such as The vacuum insulation panel of present embodiment is such, in the case where being the composition turned back using return portion 12c, once leading portion portion Hot melt adhesive is also coated on 12a, then when anti-condensation pipe 14 is arranged, the face for being coated with hot melt adhesive will expose, operator Hand etc. is possible to attachment bonding agent 15.It is fabricated to leading portion portion 12a as a result, and passes through the fixed structure of double faced adhesive tape 17, energy A possibility that enough cancel job persons touch hot melt adhesive when the operation of anti-condensation pipe 14 is arranged, so as to prevent operating environment The problem of variation.

In addition, in refrigerator 1, from leading portion portion 12a in the range of the front end on 2 front-rear direction of shell originates regulation It is to be stuck by double faced adhesive tape 17.Using double faced adhesive tape 17 vacuum insulation panel to be fixed, with Once there is gap between 9 inner surface of outer container, liquid foam heat-insulating material will be invaded wherein, then, it is possible to because of bubble Foam blisters and fixed part is detached from.At this point, fixed part disengaging not only will result only in position occur it is unstable, mainly can also Cause: leading portion portion 12a is extruded to the front end portion of flange part 9d, thus the problem of causing vacuum insulation panel to damage.

Therefore, also that is, double by being arranged close to front end side as described above, by being fixed with double faced adhesive tape 17 Face adhesive tape 17 can make even less adhesive tape amount that undesirable situation will not occur when foam blisters.

In addition, tube parts is provided in the lateral parts of shell 2 with extending in the up-down direction in refrigerator 1, it is arranged It is formed in the vacuum insulation panel of 2 lateral parts of shell in back segment portion 12b: upwardly extending and can accommodate in 2 upper and lower of shell The receiving portion 12d of 1 or more the lateral tube 13 as tube parts.Moreover, at least one receiving portion 12d is in leading portion portion 12a It is formed in a manner of opening between back segment portion 12b.

On 1 vacuum insulation panel, in order to embody thickness difference, change the amount of core material in part to be embodied, alternatively, There are also molding method is carried out to core material by pressing after evacuation, still, the method that core material flattens is possible to meeting Damage is brought to bag portion part.On the other hand, in the case where locally changing the amount of core material, be especially laminated relatively thin core material and into The enclosed method of row, although can relatively easily accomplish by adjusting its stacking number, when being laminated, The core material of all size, which mixes, to be laminated, and will lead to management, manufacture becomes complexity.

Therefore, by being formed as that receiving portion 12d is made to be open between leading portion portion 12a and back segment portion 12b, so that it may be formed Out: not being the concave shape in two sides with wall portion only in the receiving portion 12d of the unilateral U-shaped with wall portion, formed It, being capable of the opposite type and number for reducing core material when the 12d of receiving portion.

In this case, lateral tube 13 can also be arranged in return portion 12c, still, due to will increase thermal energy towards storage The leakage of room side is hidden, therefore, in the present embodiment, also to configure a certain amount of core material in the storeroom side of lateral tube 13 Mode forms receiving portion 12d.In addition, can certainly constitute are as follows: return portion 12c is only arranged and is not opened in the side return portion 12c The receiving portion 12d of mouth.
