Although not shown, the above partition heat insulating member is provided between the surface partition portion 45 of the second partition member 38 and the left wall 25 of the inner box 14 inside the inner box 14 to fix the fixture. A part of the electric wire 52 coming out of the opening 60 of 512 may be provided along the front-rear direction of the edge of the second partition member 38.

The assembly procedure of the heat insulation box 12 of the refrigerator according to the above-described embodiment will be described with reference to FIGS.
First, the division | segmentation heat insulation wall 31 and the fixing tool 51 which are shown in FIG. 1 are each manufactured. Next, as shown in FIG. 33, a fixture 511 is attached to one of the two adjacent divided heat insulation walls 31, for example, the left heat insulation wall 314 with screws 57. Next, the rear split heat insulating wall 315 is attached to the left split heat insulating wall 314 and the fixture 511 integrated. Thereby, the adjacent division | segmentation heat insulation wall 31 is connected and fixed, and the corner part of the inner right side of the inner case 14 is formed. At this time, the angle between the adjacent walls formed by the left divided heat insulating wall 314 and the rear divided heat insulating wall 315 is maintained at 90 ° corresponding to the right angle portion of the reinforcing member 55. The other corner portion of the inner box 14 is also formed by connecting and fixing the divided heat insulating wall 31 and the fixture 51. Thereby, the inner box 14 whose angle of the adjacent division | segmentation heat insulation wall 31 is 90 degrees is formed, and the rectangular parallelepiped heat insulation box 12 is formed. In addition, not only the angle of the adjacent divided heat insulating wall 31 is set to 90 °, but in this case, the angle of the adjacent divided heat insulating wall 31 is adjusted to approximately 90 °, and each corner portion of the heat insulating box 12 is approximately 90 °. It only has to be.

  Further, when the heat insulating box 12 is assembled, the first partition member 37 and the second partition member 38 are provided at predetermined positions, so that the refrigerator room 39, the vegetable room 40, the ice making room 41, and the first freezer room 42 are provided. The second freezer compartment 43 is formed, and on the front opening side of the storage compartment, the right heat insulating wall 313 and the left heat insulating wall 314 are divided into the first partition member 37 and the second partition member 38. It is fixed by connecting.

According to the said structure, there exists the following effect.
Two adjacent heat insulation walls 31 are connected and fixed by a fixture 51, whereby the heat insulation box 12 of the refrigerator 11 is formed. That is, the refrigerator 11 can be assembled by combining the divided heat insulating walls 31 and combining the divided heat insulating walls 31 with the fixture 51. Therefore, according to this embodiment, the assembling work of the refrigerator 11 becomes easier than the conventional configuration in which the heat insulating member is provided in advance in the three-dimensional inner box.

  Since the reinforcing members 55 and 82 of the fixture 51 function as an angle holding portion, the angle of the adjacent divided heat insulating walls 31 is held at 90 °. Thereby, the inner box 14 can be formed in a rectangular parallelepiped. Moreover, the combination of the division | segmentation heat insulation wall 31 becomes easy because it is the structure by which the corner | angular part of the inner box 14 is hold | maintained at 90 degrees.

  Since the fixing tool 51 is fixed at a position facing the two heat insulating members 15 adjacent to each other, the heat insulating member 15 can be fixed with the fixing tool 51 as a reference. Therefore, it is possible to easily maintain the angle of the adjacent divided heat insulating walls 31 at 90 °.

  On the front opening side of the storage room, the right split heat insulating wall 313 and the left split heat insulating wall 314 are connected and fixed by the first partition member 37 and the second partition member 38, so the right split heat insulating wall The front surface of 313 and the front surface of the left-side split heat insulating wall 314 are securely fixed. Thereby, the front opening of the inner box 14 can be prevented from opening in the left-right direction, and the inner box 14 can be prevented from being twisted, and the inner box 14 and the heat insulating box 12 can be kept in a rectangular parallelepiped.

  Since the electric wire 52 and the pipe 53 provided at the corner portion of the inner box 14 are covered with the fixture 51, it is possible to prevent food from hitting the electric wire 52 and the pipe 53, and the electric wire 52 and The piping 53 can be hidden from the user of the refrigerator 11, and the design inside the storage room can be improved.

  Since the corner heat insulating members 56 and 83 are provided in the corner portion of the inner box 14, the heat insulating effect at the corner portion can be enhanced. Further, since the corner heat insulating members 56 and 83 are covered with the fixture 51, the interior design of the storage room can be improved as described above.

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

  Since the fixing tool 51 has a cylindrical shape, and the electric wire 52, the pipe 53, and the corner heat insulating members 56, 83 are housed inside the fixing tool 51, the electric wire 52, the pipe 53, and the corner heat insulating member 56, 83 can be surely difficult to see from the user of the refrigerator 11, and the design of the interior of the storage room can be further improved.

  Since the fixture 51 has the reinforcing members 55 and 82 having an L-shaped cross section, it is possible to prevent the fixture 51 from being deformed, in particular, twisted or bent as much as possible. In addition, since the fixing covers 54 and 81 are provided on the front surfaces of the reinforcing members 55 and 82, that is, the openings having an L-shaped cross section, the fixing tool 51 can be formed into a cylindrical shape.

  Since the electric wires 52 and the pipes 53 are held by the accommodating portions 67 and 98 of the corner heat insulating members 56 and 83, the electric wires 52 and the pipes 53 can be prevented from being displaced from predetermined positions.

  Openings 59 and 60 are formed in the fixture 51, and the electric wire 52 provided at the corner portion of the inner box 14 is guided to the storage chamber side. Thereby, the electric wire 52 led to the storage chamber side from the openings 59 and 60 can be connected to the electric wire outside the fixture 51, that is, on the storage chamber side. In particular, since the electric wire 52 has a connecting portion 68 for connecting to the other electric wire at the portion of the fixing device 51 that protrudes from the openings 59 and 60, the electric wire 52 is connected to the other electric wire outside the fixing device 51. Can be easily performed.

  Moreover, the opening part 86,88 was formed in the fixing tool 51, and it was set as the structure which guides the piping 83 provided in the corner part of the inner box 14 to the storage chamber side. Thereby, the piping 83 led to the storage chamber side from the openings 86 and 88 can be connected to the piping on the storage chamber side. In particular, since the pipe 53 has a welded portion 99 that is welded to other pipes at the portions of the fixtures 51 that protrude from the openings 86 and 88, the pipe 53 is welded to the other pipes outside the fixture 51. Can be easily performed.

  Since the fixture 51 and the electric wire 52 are integrated, and the fixture 51 and the pipe 53 are integrated, when the divided heat insulating wall 31 is connected and fixed by the fixture 51, the electric wire 52 and the pipe are connected. 53 can also be provided at a predetermined corner of the divided heat insulating wall 31.
