First, the divided heat insulating wall 31 and the fixture 51 shown in FIG. 1 are manufactured respectively. Next, as shown in FIG. 33, the fixture 511 is attached to one of the two adjacent split heat insulating walls 31, for example, the left side split heat insulating wall 314, with screws 57. Next, the split heat insulating wall 315 for the back surface is attached to the one in which the split heat insulating wall 314 for the left surface and the fixture 511 are integrated. As a result, the adjacent divided heat insulating walls 31 are connected and fixed, and a corner portion on the right back side of the inner box 14 is formed. At this time, the angle of the adjacent walls formed by the left side split heat insulating wall 314 and the back side split heat insulating wall 315 is held at 90 ° corresponding to the right-angled portion of the reinforcing member 55. The other corners of the inner box 14 are also formed by connecting and fixing the split heat insulating wall 31 and the fixture 51. As a result, the inner box 14 having an angle of 90 ° between the adjacent divided heat insulating walls 31 is formed, and the rectangular parallelepiped heat insulating box body 12 is formed. In addition to setting the angle of the adjacent divided heat insulating walls 31 to 90 °, in this case, the angle of the adjacent divided heat insulating walls 31 is adjusted to approximately 90 °, and each corner of the heat insulating box 12 is approximately 90 °. It should be.

Further, by providing the first partition member 37 and the second partition member 38 at predetermined positions when assembling the heat insulating box body 12, the refrigerating chamber 39, the vegetable compartment 40, the ice making chamber 41, and the first freezing chamber 42 are provided. And the second freezing chamber 43 is formed, and on the front opening side of the storage chamber, the right side divided heat insulating wall 313 and the left side divided heat insulating wall 314 are the first partition member 37 and the second partition member 38.

That is, the refrigerator 11 can be assembled by combining the divided heat insulating walls 31 and combining these divided heat insulating walls 31 with the fixture 51. Therefore, according to this embodiment, the assembly work of the refrigerator 11 becomes easier than the conventional configuration in which the heat insulating member is provided in the three-dimensional inner box in advance.

Since the reinforcing members 55 and 82 of the fixture 51 function as the angle holding portion, the angle of the adjacent divided heat insulating walls 31 is held at 90 °. As a result, the inner box 14 can be formed into a rectangular parallelepiped. Further, since the corners of the inner box 14 are held at 90 °, the combination of the divided heat insulating walls 31 becomes easy.

Since the fixture 51 is fixed at a position facing two heat insulating members 15 that are adjacent to each other and separated from each other, the heat insulating member 15 can be fixed with reference to the fixture 51. Therefore, the angle of the adjacent divided heat insulating walls 31 can be easily maintained at 90 °.

On the front opening side of the storage chamber, the split heat insulating wall 313 for the right side and the split heat insulating wall 314 for the left side are connected and fixed by the first partition member 37 and the second partition member 38, so that the split heat insulating wall for the right side is connected and fixed. The front surface of the 313 and the front surface of the split insulation wall 314 for the left surface are securely fixed. As a result, the front opening of the inner box 14 can be prevented from opening in the left-right direction, the inner box 14 can be prevented from twisting, and the inner box 14 and the heat insulating box body 12 can be kept in a rectangular parallelepiped shape.

Further, since the corner heat insulating members 56 and 83 are covered with the fixture 51, the design of the inside of the storage chamber can be improved as described above.

Since the corner heat insulating members 56 and 83 are arranged so as to cover the separated portions of the adjacent split heat insulating walls 31, the heat insulating effect of the portion having a small heat insulating effect by the divided heat insulating wall 31 can be supplemented. Thereby, the heat insulating effect of the entire heat insulating box 12 can be improved.
