It is a flow of molding the outline.

However, since it is difficult to simultaneously bend the dew protection pipe and the side plate, in the above manufacturing process, although it is necessary to arrange the dew protection pipe after bending the side plate, for the work of arranging the dew protection pipe Space, the vacuum insulation panel could not be arranged in advance to the side of the dewproof pipe.

Hereinafter, embodiments will be described with reference to FIGS. 1 to 11.
As shown in FIG. 1, the refrigerator 1 according to this embodiment includes a refrigerator compartment 3, a vegetable compartment 4, an ice compartment 5 and a small freezer compartment 6 arranged in the left and right, and a large freezer compartment 7 in the cabinet 2 sequentially from the top. It has multiple storage rooms. Among these, the small freezer compartment 6 functions as, for example, a storage room for quick freezing. In addition, the structure of the refrigerator 1 shown in FIG. 1 is an example, and the number, the kind, and arrangement | positioning of a storage chamber are not limited to what is shown in FIG.

  The refrigerator compartment 3 is opened and closed by the left door 3a and the right door 3b of the double doors arranged side by side. The vegetable compartment 4, the icemaker 5, the small freezer compartment 6, and the large freezer compartment 7 are opened and closed by the drawer type vegetable compartment door 4a, the icemaker door 5a, the small freezer compartment door 6a and the large freezer compartment door 7a, respectively. Moreover, although illustration is abbreviate | omitted in the left door 3a of the refrigerator compartment 3, the operation panel provided with several illumination type electrostatic switches and several illumination type display is provided.

  As shown in FIG. 2, the cabinet 2 of the refrigerator 1 is composed of an outer case 9 having an opening 8 at the front and an inner case 10 accommodated in the outer case 9. The outer box 9 is formed of a steel plate, and the inner box 10 is formed of a resin material such as plastic. Between the outer case 9 and the inner case 10, a vacuum heat insulation panel and a piping member are disposed. Moreover, a foam insulation material is filled in the part in which the vacuum insulation panel does not exist between the outer case 9 and the inner case 10.

  Specifically, between the outer box 9 and the inner box 10, a ceiling panel 11 is disposed on the ceiling as a vacuum heat insulating panel, and a side panel 12 is disposed on the side. Hereinafter, the side panel 12 disposed on the left side of the cabinet 2 is referred to as the left side panel 12A for convenience, and the side panel 12 disposed on the right side of the cabinet 2 is referred to as the right side for convenience It is called panel 12B.

  As is well known, this vacuum insulation panel is formed, for example, by laminating core materials such as glass fiber and filling it in a bag member as an exterior film, evacuating the inside of the bag member and sealing the opening. ing. Moreover, although illustration is abbreviate | omitted, a vacuum heat insulation panel is arrange | positioned also in the baseplate part and back surface part of the cabinet 2. FIG.

  In addition, a side pipe 13 is disposed on the side surface portion as a piping member between the outer case 9 and the inner case 10, and the peripheral edge of the opening 8 is from the one side surface of the cabinet 2 via the ceiling portion. A dew protection pipe 14 extending to the other side is disposed. That is, the dew proof pipe 14 is continuously provided at least on the upper side of the opening 8 and the left and right sides. These piping members are pipes for passing the refrigerant on the way from the compressor (not shown) to the cooler, and are provided to prevent the dew on the surface of the refrigerator 1.

  In addition, although the separate name is attached as the side surface pipe 13 and the dew proof pipe 14 here for simplification of description, these fulfill the same function as what is called a heat radiation pipe. Moreover, the arrangement | positioning aspect of the vacuum heat insulation panel shown in FIG. 2 and a piping member is an example, and is not limited to this.

Next, the operation of the above configuration will be described.
First, a part of the manufacturing process of the cabinet 2 will be described. The outer box 9 constituting the cabinet 2 is, as shown in FIG. 3, in a state where a top plate 9a forming a ceiling of the outer box 9, a left side plate 9b forming a side of the outer box 9 and a right side plate 9c are connected. Manufactured by molding thin sheet steel.

  Specifically, a flange portion 9d is formed on the thin steel plate by a bent portion obtained by bending a side plate at an end portion on the front side of the cabinet 2 using a cold roll forming machine or the like. The flange portion 9d forms the peripheral edge of the opening portion 8. As shown in FIG. 2 and on the inner surface side thereof, a dewproof pipe 14 is disposed as shown in FIG. 3 and described later. Ru. Further, a flange portion 9 e is formed at an end portion on the back side of the cabinet 2.

  Subsequently, the side pipe 13 is fixed to the left side plate 9b and the right side plate 9c on the surface on which the flange portion 9d of the thin steel plate is formed, that is, the inner surface of the outer box 9 by aluminum foil tape or the like. The side panel 12 to which the adhesive 15 (see FIG. 6) such as hot melt is applied on the surface on the side to be attached is fixed by the press.

  Then, the ridge line between the top plate 9a and the left side plate 9b and the ridge line between the top plate 9a and the right side plate 9c are bent at 90 degrees to form a substantially U-shaped outer shell, As shown in FIG. 4, the flange portion 9d is fitted with the inner box 10, and the flange portion 9e is fitted with the back plate 9f. Thereby, the outer case 9 and the inner case 10 are integrated, and the outer shell of the cabinet 2 is roughly formed. Also, although not shown, the bottom plate is also attached at this point.

  Now, since the dew proof pipe 14 is disposed on the peripheral edge of the opening portion 8, simply considering the step before forming the thin steel plate into a U shape, for example, the flange portion 9d is formed on the thin steel plate It is thought that it is possible to arrange the sheet steel sheet at a later stage. However, as described above, since the thin steel plate is bent at 90 degrees, if the dew proof pipe 14 is disposed in advance, there is a possibility that the dew proof pipe 14 may be damaged or crushed when it is formed into a U shape.

  Alternatively, it is also conceivable to fix the dew proof pipe 14 to the inner box 10 side and combine it with the outer box 9. However, there is a risk that the anti-dew pipe 14 may be displaced when fitted with the flange portion 9 d, and the anti-dew pipe 14 is disposed at a position close to the storage chamber and heat flows into the storage It is not preferable because it becomes a factor to increase the power consumption of the

  Therefore, in the case of the manufacturing process of forming the outer box 9 by bending the thin steel plate as described above, it is necessary to dispose the dew proof pipe 14 after bending the thin steel plate. In that case, since a work space for disposing the dew proof pipe 14 is required, the conventional vacuum heat insulation panel (hereinafter referred to as the conventional panel 112 for convenience) shown as a comparative example in FIG. In the case where the process is not changed, it has been necessary to arrange in a state of being separated from the dew proof pipe 14 disposed on the flange portion 9 d side by a distance (D) necessary for the operation.

  In other words, it is desirable that the general vacuum heat insulation panel can be disposed as wide as possible in the side portion of the cabinet 2 because the heat insulation property is superior to that of the foam heat insulation material. It was not possible to arrange the vacuum insulation panel up to the last position on the side of the flange 9 d for the work of attaching the pipe 14. Therefore, there is room for improvement in the improvement of the heat insulation performance and the suppression of the heat inflow into the storage room.

  Therefore, in the present embodiment, the vacuum heat insulation panel may be disposed close to the dew proof pipe 14, that is, as close to the dew proof pipe 14 as it is, without changing the main manufacturing process as follows. I am able to do it.

  FIG. 5 schematically shows a left side panel 12A disposed on the left side of the cabinet 2 among the vacuum insulation panels disposed between the outer casing 9 and the inner casing 10. However, FIG. 5 intentionally shows details in detail for the purpose of explanation, and there are parts that are different from the actual size and size. Further, although the detailed description is omitted, the right side panel 12B disposed on the right side portion of the cabinet 2 is formed in a shape symmetrical to the left side panel 12A with respect to the center of the cabinet 2 (see FIG. 9).

  The left side panel 12A is roughly composed of a front end 12a, a rear end 12b, and a turn back 12c connecting the front end 12a and the rear end 12b. The left side panel 12A is disposed such that the front stage 12a is on the front side of the cabinet 2 and the rear stage 12b is on the back side of the cabinet 2, and the vertical direction in the drawing is along the vertical direction of the cabinet 2. Further, in FIG. 5, the rear side in the drawing is the outer box 9 side, and the front side in the drawing is the inner box 10 side.

  The thickness (L1) of the front stage 12a is set smaller than the thickness (L2) of the rear stage 12b. A folded back portion 12c is formed between the front end 12a and the rear end 12b, that is, in the middle of the cabinet 2 in the front-rear direction. However, the thickness (L 1) of the front stage 12 a is set smaller than the width of the flange 9 d in the left-right direction of the cabinet 2.

  The folded back portion 12c is formed to extend in the vertical direction of the cabinet 2, and the thickness (L3) thereof is set smaller than the front end 12a and the rear end 12b. The folded portion 12c is formed by not filling the core material, or by making the thickness of the core material to be filled thinner than other portions, and has a certain degree of flexibility. A cloth-like core material is used, and the core member is not disposed at the folded portion 12c, or the number of laminated layers is reduced.

  The width (L4) of the folded portion 12c is set larger than the thickness (L1) of the front portion 12a and the thickness (L2) of the rear portion 12b. Thereby, as described later, the left side panel 12A can be folded back at the folding portion 12c (see FIG. 6). Further, at the outer box 9 side of the rear part 12b, one or more, in the present embodiment, two accommodation parts 12d for accommodating the side pipe 13 are formed.

  The housing portion 12d can be formed by providing a portion in which the number of laminated core members is reduced, or by applying a pressure such as pressing a mold after forming the vacuum heat insulation panel. Further, among the housing portions 12d, those closest to the front end portion 12a, that is, those on the folded back portion 12c side are opened to the folded back portion 12c side. In addition, the number and the position of the accommodating part 12d can be suitably selected according to the number and the position of the side surface pipe 13.

  Such a left side panel 12A can be easily bent in the front-rear direction at the folded portion 12c because the folded portion 12c has flexibility. Specifically, the adhesive 15 is not applied to the left side panel 12A and the front stage 12a, and the adhesive 15 is applied to the rear stage 12b and placed on a thin steel plate as shown in FIG. By pressing, the rear end 12b side is first firmly bonded to the thin steel plate. At this time, since the adhesive 15 is not applied to the front stage 12a, the front stage 12a is not bonded to the thin steel plate.

  Then, before or after being bent in a U-shape, the front portion 12a is bent to overlap the rear portion 12b as shown in FIG. A larger working space can be secured between the left side panel 12A and the flange portion 9d and the rear stage 12b more strictly.

  Subsequently, by using the large work space, as shown in FIG. 7, it is possible to easily accommodate and fix the dew proof pipe 14 in the space formed on the inner surface side of the flange portion 9d. . At this time, since the front stage 12a is temporarily fixed, it does not interfere with work.

  Thereafter, as shown in FIG. 8, the tape 16 is removed, and the double-sided tape 17 is attached to be biased toward the front end side of the front part 12a, and the front part 12a is positioned on the flange 9d side and attached to the left side plate 9b. The left side panel 12A can be disposed in a state in which the left side panel 12A is in close proximity to the flange portion 9d. In this case, the flange portion 9d may not be in contact with the flange portion 9d. The right side panel 12B is also disposed in the same process.

  At this time, in the left side panel 12A, the distance (L5) between the front part 12a and the rear part 12b in the disposed state is shorter than the width (L4) of the folded part 12c in the molded state. It is arranged as That is, the left side panel 12A is formed such that the length in the front-rear direction at the time of molding exceeds the flange 9d, and the combined length of the front stage 12a and the rear stage 12b does not reach the flange 9d. It is formed to a degree.

  And, in the state where the left side panel 12A is disposed, the width of the folded portion 12c becomes relatively small, so that the core material is not filled, or the core material is thinner than the other portions, so the heat insulation performance is improved. The gap occupied by the relatively low folded-back portion 12c is smaller. At this time, the bag member is disposed in a state of being wrinkled.

  After that, when the attachment of the back plate 9f and the bottom plate is completed, as shown in FIG. 9, for example, a liquid foam heat insulating material is indicated by an arrow H from the inlet 18 provided in the back plate 9f. Be injected. At this time, the foamed heat insulating material is injected in a state where the flange portion 9 d is in the downward direction of gravity, and the foamed heat insulating material foams, that is, the foamed heat insulating material expands upward and is filled.

  Therefore, in the region (R) on the side of the flange portion 9d where the thickness of the front end portion 12a is relatively thin, the filling property can be enhanced by spreading in the horizontal direction before it is expanded. Further, since the left side panel 12A and the right side panel 12B are fixed by the double-sided tape 17 on the front end side, they are prevented from being peeled off when the injected foam heat insulating material foams.

According to the embodiment described above, the following effects can be obtained.
In the refrigerator 1 of the embodiment, the dewproof pipe 14 as a piping member is disposed on the periphery on the opening 8 side between the outer case 9 and the inner case 10, and the side panel 12 as the vacuum heat insulation panel is A folded portion 12c in which the core material is not filled or the thickness of the filled core material is thinner than other portions is formed, and the front side of the cabinet 2 with respect to the folded portion 12c is also provided. The front stage portion 12a, which is a portion of the front end portion 12a, is formed to be foldable in the rear stage portion 12b, which is a rear side portion of the folded back portion 12c.

  As a result, the vacuum heat insulation panel can be easily bent at the folded back portion 12c, so that a working space for the dew proof pipe 14 disposed at the periphery of the opening 8 can be secured, and the front stage 12a is on the dew proof pipe 14 side. It becomes possible to arrange as close as possible. In addition, since the rear stage 12b can be fixed by pressing, it can be firmly bonded. Therefore, the vacuum insulation panel can be moved to the dew proof pipe 14 without changing the main manufacturing process.

  Moreover, in the refrigerator 1, the width (L4) of the folded back portion 12c in the front-rear direction of the cabinet 2 is formed longer than the thickness of the front portion 12a and the rear portion 12b. As a result, the front stage 12a can be folded back and fixed approximately 180 degrees on the rear stage 12b side, and flexibility required for folding back can be secured, and temporary fastening can be easily performed.

Further, in the refrigerator 1, the vacuum heat insulation panel is disposed such that the distance (L5) between the front stage 12a and the rear stage 12b in the disposed state is shorter than the width (L4) of the folded back at the time of molding It is set up.
If the front portion 12a is attached in a state where the folded portion 12c is pulled in the front-rear direction, the heat insulating performance is deteriorated in the thin portion of the core material. Further, there is also a possibility that the front end side of the vacuum insulation panel, that is, the front end side of the front portion 12a does not reach the flange 9d, due to the variation in the width in the front-rear direction in manufacturing the vacuum insulation panel.

  Therefore, by arranging the folded portion 12c having flexibility as described above to make the bag member be in a wrinkled state, it is possible to absorb variations in dimensions and the like, and it is necessary to provide the most heat insulation. The vacuum heat insulation panel can be reliably covered up to the vicinity of the flange part 9d which is one of the parts to be used, and furthermore, the gap between the front part 12a and the rear part 12b is narrowed to be necessary as the cabinet 2 Thermal insulation performance can also be ensured.

Moreover, in the refrigerator 1, as for the vacuum heat insulation panel, the thickness of the front | former stage part 12a is thinner than the thickness of the back | latter stage 12b. And, in the embodiment, the thickness (L1) of the front stage 12a is set smaller than the width of the flange 9d.
When the vacuum insulation panel is disposed close to the flange portion 9d, if the filling of the foam insulation is prevented by the vacuum insulation panel, the foam insulation does not extend to the space in which the dew proof pipe 14 is accommodated, and insulation is provided. Performance may be reduced. When the foam heat insulating material is filled in the cabinet 2, the cabinet 2 is usually performed with the opening 8 side down.

  Therefore, by making the thickness of the front portion 12a relatively thin, a space for filling the foamed heat insulating material can be secured, and the filling property can be improved, and a vacuum for securing the space is also ensured. It can prevent that the thickness of a heat insulation panel becomes thin in the whole side, and it can prevent that heat insulation performance falls.

  Further, by making the thickness of the front portion 12a relatively thin, the possibility of touching the end of the flange 9d formed by bending the tip of the cut surface of the left side plate 9b can be reduced, and a vacuum heat insulation panel Can prevent damage to the vacuum state, that is, a decrease in heat insulation performance. Moreover, since the front side of the refrigerator 1 is a part where the structures are relatively concentrated, it is possible to prevent the structures from interfering with the vacuum heat insulation panel by relatively reducing the thickness of the front portion 12a.

  In the refrigerator 1, the vacuum insulation panel is attached to the inner surface of the outer box 9 by the double-sided tape 17 with the front stage 12 a, while the rear part 12 b is attached to the inner surface of the outer box 9 by the adhesive 15. There is.

  The conventional general vacuum insulation panel is attached by an adhesive 15 such as a hot melt, but in the case of a configuration in which the folded back portion 12c is folded back like the vacuum insulation panel of this embodiment, the front stage 12a is also hot When the melt is applied, the surface on which the hot melt is applied may be exposed when the dew protection pipe 14 is disposed, and the adhesive 15 may be adhered to the hand of the operator or the like. Therefore, by fixing the front end portion 12a with the double-sided tape 17, there is no possibility of the operator touching the hot melt at the time of the operation of arranging the dew protection pipe 14, and the working environment can be prevented from being deteriorated.

  Further, in the refrigerator 1, a predetermined range from the front end in the front-rear direction of the cabinet 2 is pasted by the double-sided tape 17 in the front stage 12 a. In the case where the vacuum heat insulation panel is fixed by the double-sided tape 17, if there is a gap between it and the inner surface of the outer box 9, the liquid foam heat insulating material enters and there is a risk that the fixed part may be peeled off by foaming. At this time, peeling off of the fixed part not only makes the position unstable but also causes the vacuum insulation panel to be damaged by being pressed against the end of the flange 9 d.

  Therefore, by fixing with the double-sided tape 17 as described above, that is, by providing the double-sided tape 17 biased toward the front end side, it is possible to prevent a problem at the time of foaming even with a small amount of tape.

  Further, in the refrigerator 1, the piping member is disposed extending in the vertical direction also on the side surface portion of the cabinet 2, and the vacuum heat insulation panel disposed on the side surface portion of the cabinet 2 is a piping member on the rear stage portion 12 b One or more accommodation portions 12 d for accommodating the side pipes 13 as the upper and lower sides of the cabinet 2 are formed to extend in the vertical direction of the cabinet 2. And at least one accommodating part 12d is opened and formed between the front | former stage part 12a and the back | latter stage 12b.

  In order to make the thickness difference in a single vacuum insulation panel, there is a method of changing the amount of the core material partially or vacuum drawing and then molding the core material by pressing, but the core material is crushed The method may damage the bag member. On the other hand, when the amount of core material is partially changed, although the method of laminating and sealing thin core materials in particular can be made relatively easily by adjusting the number of cores, cores of various sizes can be produced when laminating. The materials are mixed and overlapped, and management and manufacturing become complicated.

  Therefore, by forming the housing portion 12d so as to open between the front portion 12a and the rear portion 12b, a U-shaped housing portion having a wall portion only on one side, not a recessed shape having a wall portion on both sides 12d can be formed, and the number and type of core members can be relatively reduced when forming the accommodating portion 12d.

  In this case, although the side pipe 13 can be disposed at the folded back portion 12c, heat leakage to the storage chamber side is increased. Therefore, in the present embodiment, a certain amount of core material is disposed also on the storage chamber side of the side pipe 13. The housing 12 d is formed as described above. Moreover, it is a matter of course that only the folded back portion 12c and the housing portion 12d which is not opened at the divided position 12e described above may be provided.

  Further, in the various configurations described above, not only the side panel 12 but also the ceiling panel 11 provided in the ceiling portion of the cabinet 2 and the bottom panel provided in the bottom are configured to be provided with the folding portion 12 c similarly to the side panel 12 It can also be done.

  Further, as shown in FIG. 10, the folded back portion 12c can also be formed at a position biased to the inner box 10 side in the thickness direction of the vacuum heat insulation panel. Specifically, it can be formed so that it may be located in the inner box 10 side rather than the half to thickness L 1 of front part 12a. Thereby, it is possible to more easily fold the front stage 12a.

  When laminating core materials, the core member on the inner box 10 side can be the largest area, that is, the area covering the entire area from the front stage 12a to the rear stage 12b, but it is folded back by vacuum evacuation. Similarly to the outer box 9 side, a slight depression is formed on the inner box 10 side as well.

  Moreover, the vacuum heat insulation panel can be set as the structure of those other than the integrated structure by which the front | former stage part 12a and the back | latter stage part 12b were connected by the folding | returning part 12c as mentioned above. Specifically, as shown in FIG. 11, the vacuum insulation panel is physically divided into two or more in the front-rear direction of the cabinet 2, and the front side of the division position 12e where the vacuum insulation panel is divided. It can form by the front | former stage part 12a which is a site | part, and the back | latter stage 12b which is a site | part back side from the division | segmentation position 12e.

  In this case, the housing portion 12d and the like can be formed in the same manner as the integral type described above, or the front stage 12a can be attached to the inner surface of the outer box 9 with the double-sided tape 17. It is also possible to attach a predetermined range from the front end with a double-sided tape 17.

  Even with such a configuration, as with the integral type, various kinds of the above-described, including the fact that the vacuum heat insulation panel can be moved to the vicinity of the flange portion 9d and hence the dew proof pipe 14 without changing the main manufacturing process. You can get the effect of In particular, in the case where the dimensions in the front-rear direction are the same as in the ceiling panel 11, the manufacturing efficiency of the vacuum thermal insulation panel can be improved because it can be realized by using two vacuum thermal insulation panels having the same shape.
