Definitions

  • the invention relates to a refrigerator.
  • a refrigerator has a structure in which a heat insulating material is filled between an outer box and an inner box, but even if there is a heat insulating material, sometimes the cold air in the inner box is transmitted to the outer box. At this time, the air around the outer box is cooled due to the temperature difference between the inside and outside of the outer box, and condensation occurs on the surface of the outer box.
  • Patent Document 1 describes that a hot gas pipe is buried in a heat insulating material filled between a partition wall partitioning each storage compartment in a refrigerator and a partition outer panel.
  • the hot gas pipe that has been used conventionally is usually made of copper.

  • the hot gas pipe 50 since copper has corresponding elasticity, the hot gas pipe makes good contact with the partition outer plate covering the partition wall front 61. Thereby, the temperature difference between inside and outside of the outer box is eased, and the anti-condensation function is effectively exerted.
  • the material of the hot air pipe 50 is changed from copper to iron, since the iron has a lower elasticity than copper, the hot air pipe 50 may not sufficiently contact the partition outer plate in the shape of one folded portion 52 as described above . Therefore, it will hinder the anti-condensation function of the outer box surface.
  • An object of the present invention is to provide a refrigerator capable of making good contact between the hot gas pipe and the partition outer plate and appropriately exerting anti-condensation even when the iron hot gas pipe is arranged in the space between the partition wall and the partition outer plate Features.

  • the partition area front part arrangement part reaches the terminal from the starting end via the first turning part and the second turning part
  • the first and second folded portions press the front cover.
  • the iron hot gas pipe further includes three straight portions that traverse a front area of the front portion of the heat-insulating partition wall, and the three straight portions are sequentially arranged at a predetermined interval in the vertical direction.
  • the outer box includes a first side wall and a second side wall opposite to the first side wall
  • the refrigerator further includes a compressor located in the machine room
