As a result, the unevenness on the surface of the vacuum heat insulating material 43 is not transferred to the design surface, so that the appearance can be prevented from being deteriorated. Moreover, by installing the vacuum heat insulating material 43 inside the warehouse, the heat intrusion into the warehouse is reduced, and an improvement in energy saving effect can be expected.
  • the foam heat insulating material 19 is filled between the front plate 41 and the vacuum heat insulating material 43 and between the back plate 44 and the vacuum heat insulating material 43. Since the vacuum heat insulating material 43 is not only separated from the front plate 41 but also the foam heat insulating material 19 is filled between the vacuum heat insulating material 43 and the front plate 41, the heat intrusion into the cabinet is further reduced. .
  • a plurality of ribs 46 may be provided on one of the upper plate 37 and the bottom plate 38 of the door 11. In this case, in the foaming step, even if the pressure received by the vacuum heat insulating material 43 from the foam heat insulating material 19 is biased, it is possible to suppress the displacement of the vacuum heat insulating material 43 from occurring.
  • the vacuum heat insulating material 43 may be disposed to be inclined with respect to the bottom plate 38 from the vertical direction.
  • the vacuum heat insulating material 43 having a larger height can be installed in the door 11 without changing the overall size of the door 11.
  • the amount of the vacuum heat insulating material 43 mounted on the door 11 is increased, and the heat insulating performance is improved.
  • a refrigerator in which a vacuum heat insulating material is disposed in close contact with a front plate of a door and a handle portion is provided on both side surfaces of the vacuum heat insulating material is known (for example, Patent Document 3).
  • the handle portions By providing the handle portions on both side surfaces of the vacuum heat insulating material, the lateral size of the vacuum heat insulating material incorporated into the door is limited.
  • the vacuum heat insulating material is shortened by the lateral method by the depth of the handle portion.
  • the thickness of the vacuum heat insulating material of a handle part will become thin only by adding a handle part to a door. In these cases, the energy saving performance is deteriorated.
  • the surface irregularities of the vacuum heat insulating material may be transferred to the design surface of the door.
  • sticking the vacuum heat insulating material to the front plate there is a concern about deterioration of design properties and an increase in manufacturing cost and working time.
