  The said vacuum heat insulating material 3 is provided with the core material and the outer packaging material which can accommodate this core material and can maintain an inside in a pressure reduction state, for example. This core material is a laminate of a plate material made of open-cell synthetic resin foam and a fiber material made of inorganic fibers and / or organic fibers. In addition, the said core material may be only any one of the said plate-shaped material or the said fibrous material. On the other hand, the urethane heat insulating material 4 is made of, for example, urethane foam (rigid urethane foam).

  A first display unit 11 is provided on the inner side of the door 2 (the outer surface of the inner wall 2b). That is, the first display unit 11 is in the refrigerator compartment 5.

  A second display unit 12 is provided on the outside of the refrigerator body 1 (the outer surface of the outer wall 1a). That is, the second display unit 12 is located on the back surface of the refrigerator body 1.

  The said 1st display part 11 is displaying the position and number of sheets of the said vacuum heat insulating material 3, as shown in FIG. More specifically, the front, back and left and right sides of the refrigerator are illustrated, and the vacuum heat insulating material 3 is hatched in the drawing of the refrigerator. That is, two pieces of the vacuum heat insulating material 3 are arranged in the vertical direction on each of the left and right side portions of the refrigerator. As described above, the display content of the first display unit 11 is fine information (complex design) that cannot be identified when scratches or dirt are attached.

  As shown in FIG. 4, the second display unit 12 displays the use of the vacuum heat insulating material 3 and the position of the first display unit 11. More specifically, the use of the vacuum heat insulating material 3 is indicated by the letters “use of vacuum heat insulating material”, and the position of the first display portion 11 is indicated by “the place and number of use are inside the refrigerator compartment door”. It is displayed with the characters “Displaying”. Thus, the display content of the second display unit 12 is rough information (simple design) that can be identified even if scratches or dirt are attached.

  The first display unit 11 and the second display unit 12 are formed of a sealing material such as a label. In addition, you may form the said 1st display part 11 and the said 2nd display part 12 by giving a stamp and a coating material directly to the outer surface of the said refrigerator main body 1 and the said door 2. FIG.

  Next, the case where this refrigerator is disassembled for the purpose of recycling or the like will be described.

  First, the presence of the vacuum heat insulating material 3 and the position of the first display unit 11 are confirmed by the second display unit 12. At this time, even if the second display unit 12 on the outside of the refrigerator main body 1 is scratched or soiled, the display content of the second display unit 12 is rough information. Can be identified.

  Thereafter, based on the confirmation of the position of the first display unit 11, the door 2 is opened, and the position and number of the vacuum heat insulating materials 3 are confirmed by the first display unit 11. At this time, since the inside of the door 2 is a place where scratches and dirt are difficult to be attached, the detailed display contents of the first display unit 11 can be reliably identified.

  And the operator can remove the said vacuum heat insulating material 3 efficiently based on confirmation of the position and the number of sheets of the said vacuum heat insulating material 3. FIG.

  According to the refrigerator having the above-described configuration, since the first display unit 11 is provided inside the door 2, detailed information (complex design) is displayed in a place where scratches and dirt are difficult to be attached, Excellent visibility.

  In addition, since the second display unit 12 is provided outside the refrigerator body 1, rough information (simple design) is displayed in a place where scratches and dirt are easily attached. ) Is easily identified. That is, the presence or absence of the vacuum heat insulating material 3 can be determined at a glance from the outside of the refrigerator.

  Thus, before disassembling the refrigerator, without overlooking the presence or absence of the vacuum heat insulating material 3, the position and number of the vacuum heat insulating materials 3 can be reliably grasped and the vacuum heat insulating material 3 is efficiently removed. be able to.

  Moreover, since the said 1st display part 11 is provided in the said door 2, and the said 2nd display part 12 is provided in the said refrigerator main body 1, even if the said refrigerator main body 1 and the said door 2 are isolate | separated, Since it can be seen that the vacuum heat insulating material 3 is used in the refrigerator, the vacuum heat insulating material 3 can be reliably separated when the refrigerator is disassembled.

  As a comparative example, when the first display unit 11 is provided outside the refrigerator main body 1 or the door 2 without providing the second display unit 12, the first display unit 11 may be damaged due to scratches or dirt. The display unit 11 becomes difficult to see and has poor visibility. Of course, when the first display unit 11 is provided inside the refrigerator body 1 or the door 2, even the presence of the vacuum heat insulating material 3 cannot be determined.

  In short, in the present invention, visibility is improved by arranging predetermined display contents at appropriate positions (that is, skillfully combining display contents and display positions). That is, display contents that can be identified even if scratches or dirt are attached are provided as the second display section 12 on the outside of the refrigerator main body 1 that is easily damaged or dirty. On the other hand, display contents that cannot be identified when scratches or dirt are attached are provided as the first display section 11 inside the door 2 that is not easily scratched or dirty.

(Second Embodiment)
FIG. 5 shows a second embodiment of the refrigerator of the present invention. The difference from the first embodiment will be described. In the second embodiment, a third display unit 13 including the first display unit 11 is provided inside the door 2 shown in FIG. It has been.

  The third display unit 13 displays information other than the information of the first display unit 11. This other information includes, for example, the performance of the refrigerator and precautions for use.

  Thus, the information of the first display unit 11 can be written together with other information by the third display unit 13, and productivity can be prevented and an increase in cost can be suppressed.

(Third embodiment)
FIG. 6 shows a third embodiment of the refrigerator of the present invention. If the point which is different from the said 1st Embodiment is demonstrated, in this 3rd Embodiment, the 4th display part 14 containing the said 2nd display part 12 will be on the outer side of the said refrigerator main body 1 shown in FIG. Is provided.

  The fourth display unit 14 displays information other than the information of the second display unit 12. This other information is, for example, usage precautions.

  As described above, the information on the second display unit 12 can be written together with other information by the fourth display unit 14, so that productivity is not impaired and an increase in cost can be suppressed.

(Fourth embodiment)
7A and 7B show a fourth embodiment of the refrigerator of the present invention. The difference from the first embodiment will be described. In the fourth embodiment, the outer wall 1a of the refrigerator body 1 in which the vacuum heat insulating material 3 is built positions the vacuum heat insulating material 3. Four positioning portions 10 are provided. The four positioning portions 10 are respectively located outside the four corners of the vacuum heat insulating material 3. That is, each of the four positioning portions 10 is provided outside the four corners of a virtual quadrangle that is larger than the vacuum heat insulating material 3. The four positioning portions 10 serve as a guide for fixing the vacuum heat insulating material 3 or attaching the vacuum heat insulating material 3 to the outer wall 1a.

  The positioning portion 10 is formed by projecting the inner surface of the outer wall 1a while the outer surface of the outer wall 1a is recessed. The positioning part 10 is formed, for example, by pressing the outer wall 1a.

  Thus, the position of the positioning part 10 can be determined from the recess of the outer surface of the outer wall 1a when viewed from the outside of the refrigerator. That is, the position of the vacuum heat insulating material 3 can be reliably determined by the recess of the outer surface of the outer wall 1a, and the work efficiency of disassembly can be improved.

  The positioning unit 10 may be combined with at least one of the first display unit 11, the second display unit 12, the third display unit 13, and the fourth display unit 14, While the effects as described in the first to third embodiments can be obtained, the position of the vacuum heat insulating material 3 can be further clarified by the dents on the outer surface of the outer wall 1a. Will improve.

  Two positioning portions 10 may be provided outside the diagonal of the virtual quadrangle (the vacuum heat insulating material 3). Alternatively, two positioning portions 10 may be provided outside both corners of one side of the virtual quadrangle (the vacuum heat insulating material 3). Alternatively, one positioning unit 10 may be provided outside one corner of the virtual quadrangle (the vacuum heat insulating material 3).

  Therefore, when the positioning portion 10 is provided outside the diagonal, it can be seen that the vacuum heat insulating material 3 is inside the diagonal, and even if the number of the recesses is reduced, the vacuum heat insulating material 3 As the position becomes clear, the number of the dents can be reduced, so that the appearance is less impaired. Moreover, when the positioning part 10 is provided on both sides of the one side, the existence of the vacuum heat insulating material 3 can be found in one of the recesses, and the same effect as described above can be obtained. Further, when one positioning portion 10 is provided outside the one corner, it becomes an indication of the presence of the vacuum heat insulating material 3, and further, the dents are reduced and the appearance is improved.

  Moreover, the shape of the said positioning part 10 is planar view and square bracket shape (key shape). That is, since the positioning unit 10 has both end portions along adjacent sides of the virtual quadrangle (the vacuum heat insulating material 3), the vacuum heat insulating material 3 is attached depending on the shape of the positioning unit 10. The direction and the position of the vacuum heat insulating material 3 can be easily determined. The positioning part 10 only needs to have one end and the other end extending in different directions, and the positioning part 10 may have a substantially arc shape.

  Moreover, the edge of the positioning part 10 has a roundness (R shape), and the workability and finish are improved. The shape of the positioning unit 10 may be a plan view, a circle, an oval, or an ellipse. Therefore, the positioning of the vacuum heat insulating material 3 is performed, and at the same time, the determination of the presence of the vacuum heat insulating material 3 is lower than the case where the shape of the positioning portion 10 is a key shape. Since the existence of 3 is known, it helps to improve the workability of dismantling.

  Moreover, the cross-sectional shape of the positioning part 10 may be a semicircular shape, a trapezoidal shape, or a combination of a semicircular shape and a trapezoidal shape, and the position of the vacuum heat insulating material 3 may be determined.

  Moreover, the protrusion dimension to the inner surface of the said outer wall 1a of the said positioning part 10 is smaller than the thickness of the said vacuum heat insulating material 3, and there is no problem on the external appearance of a refrigerator. By making the protruding dimension of the positioning portion 10 smaller than the thickness of the vacuum heat insulating material 3, the outer surface of the outer packaging material (not shown) constituting the outer portion of the vacuum heat insulating material 3 and the outer wall 1a. In between, the urethane heat insulating material 4 is obtained thicker, the amount of heat transferred from the outside of the refrigerator main body 1 to the outer packaging material can be lowered, and the heat insulating efficiency is improved. Moreover, the protrusion dimension of the positioning part 10 can be reduced, and the appearance is further improved. The protruding dimension is preferably 2 mm or less.

  Further, there is a gap between the positioning part 10 and the vacuum heat insulating material 3, and workability when the vacuum heat insulating material 3 is arranged inside the positioning part 10 is improved. In particular, when the maximum gap between the vacuum heat insulating material 3 and the positioning part 10 is 5 mm or more (for example, the distance between the apex of the positioning part 10 and the vacuum heat insulating material 3 is 5 mm or more), The urethane heat insulating material 4 can be surely filled in the gap, and the heat insulation in the gap is increased. Thus, the heat insulation property to the surface of the vacuum heat insulating material 3 on the urethane heat insulating material 4 side is increased, and the performance is improved.

  In addition, this invention is not limited to the above-mentioned embodiment. For example, the vacuum heat insulating material 3 may be provided on the door 2. Further, the vacuum heat insulating material 3 may be provided only on the door 2. Moreover, when the said vacuum heat insulating material 3 is provided in the said door 2, you may provide the positioning part which positions the said vacuum heat insulating material 3 in the outer wall 2a of the said door 2. As shown in FIG. Further, the number of the vacuum heat insulating materials 3 may be increased or decreased. Moreover, you may increase / decrease the quantity of the 1st display part 11 and the said 2nd display part 12, or the quantity of the said 3rd display part 13 and the said 4th display part 14. FIG.
