A partition cover 28 having a U-shaped cross-section opening in the wall, a heat insulating material 24 provided in the partition cover 28, a heating body 26 provided in the partition plate 22, and a cap member provided at the upper end of the partition cover 28. 30, and the partition plate 22 closes the front opening of the partition cover 28 in a state where the heat insulating material 24 and the heating body 26 are housed inside the partition cover 28.

  The partition plate 22 is made of a substantially rectangular plate-like steel plate that is elongated in the vertical direction, and has an attracting surface 22a that constitutes an attracting surface of the magnet that the gasket 10 has, and an angle portion 22b that extends rearward from both side edges of the attracting surface 22a. ing. On the back side (the heat insulating material 24 side) of the suction surface 22a, preferably on the back side where the gasket 10 abuts when the left door 8 and the right door 9 are closed, the heating element 26 is provided along the peripheral portion of the suction surface 22a. Is provided in a state in which heat exchange is possible.

  The adsorption surface 22a is provided with an opening 22c penetrating the adsorption surface 22a in at least a part of the portion where the heating body 26 does not exist, and is made of a material having a lower thermal conductivity than a steel plate constituting the partition plate 22 such as a synthetic resin. The formed lid 32 is provided so as to close the opening 22c.

  Specifically, as shown in FIG. 3, the suction surface 22 a is provided with a recess 22 d that is recessed toward the heat insulating material 24 inside the heating body 26 provided at the peripheral portion, and an opening at the bottom of the recess 22 d. 22c is provided. The lid 32 is fitted so as to fill the recess 22d provided on the suction surface 22a, and the latching claw 32a provided on the lid 32 is engaged with the peripheral edge of the opening 22c, so that the partition plate 22 is engaged. It is fixed against.

  The partition cover 28 is divided into two parts by a front partition cover 36 and a rear partition cover 38. Both the front partition cover 36 and the rear partition cover 38 are made of a material having a lower thermal conductivity than the steel plate constituting the partition plate 22 such as synthetic resin.

  In the front partition cover 36, the angle portion 22 b of the partition plate 22 is engaged to support the partition plate 22, and the heating body 26 is positioned between the front partition cover 36 and the suction surface 22 a of the partition plate 22. A space 40 sandwiched between the partition plate 22 and the front partition cover 36 is provided between the heating body 26 and the front partition cover 36 with a filler 40 made of a material having a lower thermal conductivity than the steel plate constituting the partition plate 22. Is filled with a filler 40. In this embodiment, the filler 40 is in the form of a tape such as a soft tape, and is provided on the back side of the partition plate 22 so as to sandwich the heating body 26 with the partition plate 22. Covering from. Further, the front partition cover 36 is provided with a through hole 36 b in a bottom portion 36 a facing the partition plate 22.

  The rear partition cover 38 is provided behind the front partition cover 36, and forms a heat insulating space for housing the heat insulating material 24 between the rear partition cover 36. The heat insulating material 24 housed in the heat insulating space is provided with a convex portion 24a that fits into the through hole 36b provided in the front partition cover 36, whereby the heat insulating material 24 is disposed in the through hole 36b. Yes.

  A seal member 42 extending in the vertical direction is provided outside the side wall of the rear partition cover 38. In this example, a fin-like seal member 42 is provided on the left side wall of the rear partition cover 38 provided with the hinge 34 and protrudes rearward from the back surface of the left door 8 when the left door 8 and the right door 9 are closed. The seal member 42 comes into contact with the portion 8a. Thereby, the seal member 42 seals the gap between the rotary partition 20 and the door 8 behind the gasket 10 provided on the back surface of the left door 8.

  In addition, an elastic sheet 46 formed of a soft sponge is attached to the rear surface of the rear partition cover 38 and is provided on the left door 8 when the rotary partition 20 rotates when the left door 8 is opened. While mitigating the impact on the convex part 8a, the cooling of the rear partition cover 38 by the cool air in the refrigerator compartment 2 can be relaxed, and the cooling of the rotating partition 20 can be suppressed.

  The heating body 26 is a heating source that prevents the condensation on the partition plate 22 due to a temperature difference between the inside of the refrigerator and the outside air. In the present embodiment, the heating body 26 is spirally wound around a flexible core material. It consists of a linear heater in which the heated heating wire is covered with an insulator. The heating element 26 made of this linear heater can vary the amount of heat generated by changing the winding pitch width of the heating wire in the longitudinal direction. Therefore, for example, the partition plate 22 is divided into three regions in the vertical direction, and the winding pitch width of the heating wire is set to be narrow so that the heating element 26 located in the lower region has a larger heat generation amount. The heat generation amount can be increased by setting the winding pitch width of the heating wire to be narrow at a location where condensation is likely to occur.

  A guide groove 30 a that engages with a guide pin 31 that protrudes downward from the ceiling surface of the refrigerator compartment 2 is formed on the upper end surface of the cap member 30 disposed at the upper end portion of the rotating partition 20. As the door 8 opens and closes, the guide pin 31 slides in the guide groove 30 a, so that the rotating partition 20 rotates about the hinge 34.

  In the refrigerator 1 of the present embodiment as described above, the partition plate 22 of the rotating partition 20 is heated by the heating body 26 because the opening 22c is provided in at least a part of the location where the heating body 26 does not exist. The area of the partition plate 22 can be reduced, and the amount of heat generated by the heating body 26 required to prevent condensation of the partition plate 22 can be suppressed. Therefore, it is possible to prevent dew condensation that occurs in the rotating partition 70 while suppressing power consumption, and to suppress the amount of heat of the heating element that leaks into the storage chamber.

  In the present embodiment, since the lid body 32 made of a material having lower thermal conductivity than the steel plate constituting the partition plate 22 is provided in the opening 22c provided in the partition plate 22, the heat of the heating body 26 is the lid body. 32, while preventing the amount of heat transferred to the partition plate 22 from being reduced, the outside air is less likely to enter the inside of the rotating partition 20 through the opening 22c, and the heat insulating performance of the rotating partition 20 is improved. Can be made.

  In the present embodiment, the partition cover 28 that covers the rear of the partition plate 22 is moved forward and backward by the front partition cover 36 that supports the partition plate 22 and the rear partition cover 38 that is provided behind the front partition cover 36. Since it is divided, the thermal resistance increases between the front partition cover 36 and the rear partition cover 38, and it is possible to suppress the heat of the heating body 26 from leaking into the storage chamber via the partition cover 28.

  Furthermore, since the front partition cover 36 is provided with a through hole 36b in the bottom portion 36a facing the partition plate 22, the front partition cover 36 is reduced in area in contact with the rear partition cover 38 via the heat insulating material 24. And the rear partition cover 38 can be further increased in thermal resistance, and the heat of the heating body 26 can be prevented from leaking into the storage chamber. In that case, since the convex part 24a of the heat insulating material 24 is provided in the through hole 36b provided in the front partition cover 36, the air inside the rotating partition 20 passes through the through hole 36b and the front partition cover 36. It is possible to prevent back and forth between the front and rear spaces, and to prevent the heat of the heating body 26 from leaking into the storage chamber via the air inside the rotating partition 20.

  Further, when an air layer exists between the partition plate 22 and the front partition cover 36, the air in the air layer is convected by the heat of the heating body 26, and the heat of the heating body 26 diffuses into the rotating partition 20. However, in this embodiment, since the filler 40 made of a material having a lower thermal conductivity than the steel plate constituting the partition plate 22 is provided between the heating body 26 and the front partition cover 36, The air layer formed between the partition cover 36 can be reduced, and a decrease in the heating efficiency to the partition plate 22 due to the heat of the heating body 26 diffusing into the rotary partition 20 can be suppressed. In addition, in this embodiment, the filler 40 is provided on the back side of the partition plate 22 so as to sandwich the heating body 26 between the partition plate 22 and covers the heating body 26 from the outside. In contrast, the heat from the heating body 26 can be concentrated on the partition plate 22 having a lower thermal resistance, and the partition plate 22 can be efficiently heated.

  Moreover, since the heating body 26 that heats the partition plate is provided on the back side of the partition plate 22 at the position where the gasket 10 abuts when the left and right doors 8 and 9 are closed, it is difficult to ensure heat insulation performance and condensation easily occurs. The position of the gasket 10 provided on the doors 8 and 9 can be heated preferentially, and the amount of heat generated by the heating body 26 required to prevent the condensation of the partition plate 22 can be suppressed.

  Further, in the present embodiment, since the linear heater constituting the heating body 26 can adjust the heat generation amount by changing the winding pitch width of the heating wire in the longitudinal direction, the heating body 26 is partially meandered. For example, the heat generation amount can be partially adjusted without changing the density at which the heating body 26 is disposed. Therefore, even if the location where the heating body 26 can be disposed is limited by providing the opening 22 c in the partition plate 22, the amount of heat generated by the heating body 26 depends on the position of the partition plate 22. Easy to adjust.

  In addition, although this embodiment demonstrated the case where the cover body 32 provided in the opening part 22c of the partition plate 22 was fitted in the opening part 22c from the outer side of the rotation partition 20 as shown in FIG. 4, the insulating plate 24 may be fitted into the opening 22c from the back side of the partition plate 22 as illustrated in FIG. 4, and further, as illustrated in FIG. 5, the heat insulating material 24 housed inside the rotating partition 20. The lid portion may be provided in the opening portion 22c by fitting the convex portion 24b provided on the opening portion 22c of the partition plate 22 as a lid body.

  As mentioned above, although embodiment of this invention was described, these embodiment was shown as an example and is not intending limiting the range of invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof as well as included in the scope and gist of the invention.
